Vulnerability from github – Published: 2024-09-04 21:30 – Updated: 2024-10-09 15:32In the Linux kernel, the following vulnerability has been resolved:
KVM: s390: fix validity interception issue when gisa is switched off
We might run into a SIE validity if gisa has been disabled either via using kernel parameter "kvm.use_gisa=0" or by setting the related sysfs attribute to N (echo N >/sys/module/kvm/parameters/use_gisa).
The validity is caused by an invalid value in the SIE control block's gisa designation. That happens because we pass the uninitialized gisa origin to virt_to_phys() before writing it to the gisa designation.
To fix this we return 0 in kvm_s390_get_gisa_desc() if the origin is 0. kvm_s390_get_gisa_desc() is used to determine which gisa designation to set in the SIE control block. A value of 0 in the gisa designation disables gisa usage.
The issue surfaces in the host kernel with the following kernel message as soon a new kvm guest start is attemted.

Vulnerability from github – Published: 2025-06-19 15:30 – Updated: 2025-09-22 21:30In the Linux kernel, the following vulnerability has been resolved:
NFSv4: Fix free of uninitialized nfs4_label on referral lookup.
Send along the already-allocated fattr along with nfs4_fs_locations, and drop the memcpy of fattr. We end up growing two more allocations, but this fixes up a crash as:

GHSA-CP59-HF68-P4RG
Vulnerability from github – Published: 2025-06-18 12:30 – Updated: 2025-11-14 18:31In the Linux kernel, the following vulnerability has been resolved:
kcm: fix strp_init() order and cleanup
strp_init() is called just a few lines above this csk->sk_user_data check, it also initializes strp->work etc., therefore, it is unnecessary to call strp_done() to cancel the freshly initialized work.
And if sk_user_data is already used by KCM, psock->strp should not be touched, particularly strp->work state, so we need to move strp_init() after the csk->sk_user_data check.
This also makes a lockdep warning reported by syzbot go away.

Vulnerability from github – Published: 2025-02-27 03:34 – Updated: 2025-11-03 21:32In the Linux kernel, the following vulnerability has been resolved:
wifi: wcn36xx: fix channel survey memory allocation size
KASAN reported a memory allocation issue in wcn->chan_survey due to incorrect size calculation. This commit uses kcalloc to allocate memory for wcn->chan_survey, ensuring proper initialization and preventing the use of uninitialized values when there are no frames on the channel.

Mitigation
Explicitly initialize the resource before use. If this is performed through an API function or standard procedure, follow all required steps.
Mitigation
Pay close attention to complex conditionals that affect initialization, since some branches might not perform the initialization.
Mitigation
Avoid race conditions (CWE-362) during initialization routines.
Mitigation
Run or compile the product with settings that generate warnings about uninitialized variables or data.
No CAPEC attack patterns related to this CWE.
