GHSA-HPC7-GCQM-58FV
Vulnerability from github – Published: 2026-01-27 18:32 – Updated: 2026-03-20 15:31Issue summary: PBMAC1 parameters in PKCS#12 files are missing validation which can trigger a stack-based buffer overflow, invalid pointer or NULL pointer dereference during MAC verification.
Impact summary: The stack buffer overflow or NULL pointer dereference may cause a crash leading to Denial of Service for an application that parses untrusted PKCS#12 files. The buffer overflow may also potentially enable code execution depending on platform mitigations.
When verifying a PKCS#12 file that uses PBMAC1 for the MAC, the PBKDF2 salt and keylength parameters from the file are used without validation. If the value of keylength exceeds the size of the fixed stack buffer used for the derived key (64 bytes), the key derivation will overflow the buffer. The overflow length is attacker-controlled. Also, if the salt parameter is not an OCTET STRING type this can lead to invalid or NULL pointer dereference.
Exploiting this issue requires a user or application to process a maliciously crafted PKCS#12 file. It is uncommon to accept untrusted PKCS#12 files in applications as they are usually used to store private keys which are trusted by definition. For this reason the issue was assessed as Moderate severity.
The FIPS modules in 3.6, 3.5 and 3.4 are not affected by this issue, as PKCS#12 processing is outside the OpenSSL FIPS module boundary.
OpenSSL 3.6, 3.5 and 3.4 are vulnerable to this issue.
OpenSSL 3.3, 3.0, 1.1.1 and 1.0.2 are not affected by this issue as they do not support PBMAC1 in PKCS#12.

GHSA-HPP4-8VC7-9FH4
Vulnerability from github – Published: 2024-05-19 09:34 – Updated: 2026-05-12 12:31In the Linux kernel, the following vulnerability has been resolved:
net/rds: fix possible cp null dereference
cp might be null, calling cp->cp_conn would produce null dereference
[Simon Horman adds:]
Analysis:
-
cp is a parameter of __rds_rdma_map and is not reassigned.
-
The following call-sites pass a NULL cp argument to __rds_rdma_map()
-
rds_get_mr()
-
rds_get_mr_for_dest
-
Prior to the code above, the following assumes that cp may be NULL (which is indicative, but could itself be unnecessary)
trans_private = rs->rs_transport->get_mr( sg, nents, rs, &mr->r_key, cp ? cp->cp_conn : NULL, args->vec.addr, args->vec.bytes, need_odp ? ODP_ZEROBASED : ODP_NOT_NEEDED);
-
The code modified by this patch is guarded by IS_ERR(trans_private), where trans_private is assigned as per the previous point in this analysis.
The only implementation of get_mr that I could locate is rds_ib_get_mr() which can return an ERR_PTR if the conn (4th) argument is NULL.
- ret is set to PTR_ERR(trans_private). rds_ib_get_mr can return ERR_PTR(-ENODEV) if the conn (4th) argument is NULL. Thus ret may be -ENODEV in which case the code in question will execute.
Conclusion: * cp may be NULL at the point where this patch adds a check; this patch does seem to address a possible bug

"details": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet/rds: fix possible cp null dereference\n\ncp might be null, calling cp-\u003ecp_conn would produce null dereference\n\n[Simon Horman adds:]\n\nAnalysis:\n\n* cp is a parameter of __rds_rdma_map and is not reassigned.\n\n* The following call-sites pass a NULL cp argument to __rds_rdma_map()\n\n - rds_get_mr()\n - rds_get_mr_for_dest\n\n* Prior to the code above, the following assumes that cp may be NULL\n (which is indicative, but could itself be unnecessary)\n\n\ttrans_private = rs-\u003ers_transport-\u003eget_mr(\n\t\tsg, nents, rs, \u0026mr-\u003er_key, cp ? cp-\u003ecp_conn : NULL,\n\t\targs-\u003evec.addr, args-\u003evec.bytes,\n\t\tneed_odp ? ODP_ZEROBASED : ODP_NOT_NEEDED);\n\n* The code modified by this patch is guarded by IS_ERR(trans_private),\n where trans_private is assigned as per the previous point in this analysis.\n\n The only implementation of get_mr that I could locate is rds_ib_get_mr()\n which can return an ERR_PTR if the conn (4th) argument is NULL.\n\n* ret is set to PTR_ERR(trans_private).\n rds_ib_get_mr can return ERR_PTR(-ENODEV) if the conn (4th) argument is NULL.\n Thus ret may be -ENODEV in which case the code in question will execute.\n\nConclusion:\n* cp may be NULL at the point where this patch adds a check;\n this patch does seem to address a possible bug",

Mitigation MIT-56
For any pointers that could have been modified or provided from a function that can return NULL, check the pointer for NULL before use. When working with a multithreaded or otherwise asynchronous environment, ensure that proper locking APIs are used to lock before the check, and unlock when it has finished [REF-1484].
Mitigation
Select a programming language that is not susceptible to these issues.
Mitigation
Check the results of all functions that return a value and verify that the value is non-null before acting upon it.
Mitigation
Identify all variables and data stores that receive information from external sources, and apply input validation to make sure that they are only initialized to expected values.
Mitigation
Explicitly initialize all variables and other data stores, either during declaration or just before the first usage.
