Title
hsr: Prevent use after free in prp_create_tagged_frame()
Summary
In the Linux kernel, the following vulnerability has been resolved:
hsr: Prevent use after free in prp_create_tagged_frame()
The prp_fill_rct() function can fail. In that situation, it frees the
skb and returns NULL. Meanwhile on the success path, it returns the
original skb. So it's straight forward to fix bug by using the returned
value.

Title
Kernel: gsm multiplexing race condition leads to privilege escalation
Summary
A race condition was found in the GSM 0710 tty multiplexor in the Linux kernel. This issue occurs when two threads execute the GSMIOC_SETCONF ioctl on the same tty file descriptor with the gsm line discipline enabled, and can lead to a use-after-free problem on a struct gsm_dlci while restarting the gsm mux. This could allow a local unprivileged user to escalate their privileges on the system.
Severity
CWE
- CWE-366 - Race Condition within a Thread

Title
tls: fix race between tx work scheduling and socket close
Summary
In the Linux kernel, the following vulnerability has been resolved:
tls: fix race between tx work scheduling and socket close
Similarly to previous commit, the submitting thread (recvmsg/sendmsg)
may exit as soon as the async crypto handler calls complete().
Reorder scheduling the work before calling complete().
This seems more logical in the first place, as it's
the inverse order of what the submitting thread will do.

9.8 (Critical)

No local access to the target is needed.\nAC:L - The attacker controls both sides of the race \u2014 one side issues the sendmsg that leaves an async encryption in flight, the other issues the close that blocks in tls_encrypt_async_wait() and then frees ctx \u2014 and can retry across thousands of concurrent connections at no cost. No memory layout or victim state outside the attacker\u0027s influence is required.\nPR:N - A kTLS-offloading HTTPS server accepts connections from arbitrary unauthenticated clients with no client certificate in the typical deployment; locally, setsockopt(TCP_ULP,\"tls\") plus TLS_TX requires no capability at all once the tls module is loaded. Neither path needs an account or privilege on the target.\nUI:N - The race fires during ordinary kTLS record encryption and socket teardown on an established connection. No action by any local user or administrator is required.\nS:U - The use-after-free on struct tls_sw_context_tx and the resulting timer/workqueue corruption all occur in kernel memory managed by the same security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - After kfree(ctx) the callback and the later timer expiry re-read freed, attacker-groomable memory \u2014 timer-\u003efunction, dwork-\u003ewq, and tx_work-\u003esk, the last of which is dereferenced as a struct sock * by tx_work_handler/tls_tx_records. Controlling that fake sock and the redirected call is leverageable into arbitrary kernel memory disclosure.\nI:H - The stale callback performs an atomic bit-set into the reallocated slab object at a fixed offset and writes dwork-\u003ewq, dwork-\u003ecpu and timer-\u003eexpires into freed memory, then links that freed object into the global timer wheel. That yields a controlled heap write plus a function pointer read from reclaimed memory, i.e. a control-flow hijack primitive.\nA:H - Arming a delayed_work inside a freed slab object after cancel_delayed_work_sync() reliably produces slab and timer-wheel corruption, and tx_work_handler running against an already-freed TLS context oopses on the stale sk. Any of these panics the kernel."

Title
wifi: iwlwifi: fix a memory corruption
Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: iwlwifi: fix a memory corruption
iwl_fw_ini_trigger_tlv::data is a pointer to a __le32, which means that
if we copy to iwl_fw_ini_trigger_tlv::data + offset while offset is in
bytes, we'll write past the buffer.

Reaching the vulnerable merge requires local presence on the system (module/firmware load or the debugfs time-point/clear handlers), so this is Local rather than Adjacent.\nAC:L - The out-of-bounds write is fully deterministic \u2014 whenever two triggers share a time point and the newer one lacks IWL_FW_INI_APPLY_POLICY_OVERRIDE_DATA with non-empty existing data, the byte offset is unconditionally multiplied by four. There is no race, no memory-layout precondition, and INI debug is enabled by default, so no unusual configuration is needed.\nPR:L - Triggering requires only local access to the code path that (re)initializes the iwlwifi firmware debug configuration, with no authentication step in the path itself and no capability check inside iwl_dbg_tlv_override_trig_node. Between low and high privileges this is scored as the higher-severity Low, consistent with other locally-triggered iwlwifi memory-corruption CVEs.\nUI:N - No victim action is required \u2014 the trigger list is merged automatically at IWL_FW_INI_TIME_POINT_EARLY during normal firmware load, which occurs at boot or whenever the device is brought up.\nS:U - The overflow corrupts kernel slab memory and its impact is confined to the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The heap overflow writes past the krealloc\u0027d node into adjacent slab objects, corrupting neighbouring kernel structures such as pointers and length fields, which can be leveraged into an arbitrary kernel read primitive and disclosure of arbitrary memory.\nI:H - This is an out-of-bounds heap write of attacker-influenced content whose length (roughly 3 x data_len) and payload both come from the trigger TLV, giving a shaped write into adjacent slab objects \u2014 the standard primitive for kernel data/control-flow corruption and privilege escalation.\nA:H - Slab corruption of adjacent objects reliably produces kernel oopses, allocator BUG_ON/hardened-usercopy panics, or later crashes on freeing the smashed neighbours, resulting in a complete denial of service."

Title
tomoyo: fix UAF write bug in tomoyo_write_control()
Summary
In the Linux kernel, the following vulnerability has been resolved:
tomoyo: fix UAF write bug in tomoyo_write_control()
Since tomoyo_write_control() updates head->write_buf when write()
of long lines is requested, we need to fetch head->write_buf after
head->io_sem is held. Otherwise, concurrent write() requests can
cause use-after-free-write and double-free problems.
Severity

Title
IB/hfi1: Fix sdma.h tx->num_descs off-by-one error
Summary
In the Linux kernel, the following vulnerability has been resolved:
IB/hfi1: Fix sdma.h tx->num_descs off-by-one error
Unfortunately the commit `fd8958efe877` introduced another error
causing the `descs` array to overflow. This reults in further crashes
easily reproducible by `sendmsg` system call.

}
If an SDMA send consists of exactly 6 descriptors and requires dword
padding (in the 7th descriptor), the sdma_txreq descriptor array is not
properly expanded and the packet will overflow into the container
structure. This results in a panic when the send completion runs. The
exact panic varies depending on what elements of the container structure
get corrupted. The fix is to use the correct expression in
_pad_sdma_tx_descs() to test the need to expand the descriptor array.
With this patch the crashes are no longer reproducible and the machine is
stable.

Title
cifs: fix underflow in parse_server_interfaces()
Summary
In the Linux kernel, the following vulnerability has been resolved:
cifs: fix underflow in parse_server_interfaces()
In this loop, we step through the buffer and after each item we check
if the size_left is greater than the minimum size we need. However,
the problem is that "bytes_left" is type ssize_t while sizeof() is type
size_t. That means that because of type promotion, the comparison is
done as an unsigned and if we have negative bytes left the loop
continues instead of ending.

Title
net/ipv6: avoid possible UAF in ip6_route_mpath_notify()
Summary
In the Linux kernel, the following vulnerability has been resolved:
net/ipv6: avoid possible UAF in ip6_route_mpath_notify()
syzbot found another use-after-free in ip6_route_mpath_notify() [1]
Commit f7225172f25a ("net/ipv6: prevent use after free in
ip6_route_mpath_notify") was not able to fix the root cause.
We need to defer the fib6_info_release() calls after
ip6_route_mpath_notify(), in the cleanup phase.

"value": "AV:L - The vulnerability is triggered by an RTM_NEWROUTE message sent over an AF_NETLINK/NETLINK_ROUTE socket via sendmsg(), which requires local access to the system. There is no remote packet-processing path into ip6_route_multipath_add().\nAC:L - The attacker creates both sides of the condition: they drop the last reference themselves and can widen the window arbitrarily by supplying many nexthops, by setting RTA_EXPIRES=0 so the non-rtnl gc softirq reaps the route, and by lowering net.ipv6.route.gc_interval inside their own netns, with unlimited retries. syzbot reproduced it, confirming reliable triggerability.\nPR:L - rtnetlink_rcv_msg() only requires netlink_net_capable(skb, CAP_NET_ADMIN), which is evaluated against the network namespace\u0027s user namespace, so any unprivileged local user obtains it with `unshare -Urn`. Multipath ECMP routes are addable in that namespace using RTNH_F_ONLINK gateways, which bypasses gateway reachability validation.\nUI:N - The entire sequence is performed by the attacker\u0027s own process in a single netlink transaction; no victim action, mount, or other interaction is needed.\nS:U - The use-after-free corrupts kernel heap memory and is exploited within the same kernel security authority; no VM, IOMMU, or hypervisor boundary is crossed.\nC:H - rt6_fill_node() reads the freed kmalloc-512 fib6_info and copies its contents into an RTM_NEWROUTE netlink message returned to the attacker\u0027s socket, including dereferencing pointers taken from freed memory such as rt-\u003efib6_metrics (passed to rtnetlink_put_metrics()), rt-\u003efib6_table, and rt-\u003efib6_nh. Reclaiming the freed slot with controlled data turns this into an arbitrary kernel-memory read leaked directly to userspace.\nI:H - This is a use-after-free on a 512-byte kmalloc object that an unprivileged attacker can spray and reclaim, after which the kernel dereferences attacker-controlled pointers and performs a list_for_each_entry_safe() walk over the freed fib6_siblings list head. That yields controlled pointer traversal and corruption suitable for privilege escalation.\nA:H - The KASAN slab-use-after-free in rt6_fill_node() causes an oops/panic when the freed object is unmapped, poisoned, or reclaimed with invalid pointers, and it can be triggered repeatedly to reliably crash the kernel."

Sightings and recorded dates, grouped by day · UTC
How durations are calculated
Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.
Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
