In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mld: don't dereference a pointer before NULL checking it In iwlmldremovelink, the link-fwid is saved at the beginning of the function so we have it after we freed the link. But the link pointer can be NULL, and is...

UBUNTU-CVE-2026-64468

In the Linux kernel, the following vulnerability has been resolved: binder: fix UAF in binderfreetransaction In binderfreetransaction, the t-toproc is read under the t-lock. However, once the t-lock is dropped, the toproc can die in parallel. This leads to a use-after-free error when we attempt t...

CVE-2026-51296

SQLite 3.41 contains a use-after-free in the JSON module’s jsonRemoveFunc: the parsed JSON object is freed at line 3555, but jsonLookupStep is called with the released pointer at line 3575. This can allow remote attackers to crash the service and potentially leak heap information. No remediation ...

CVE-2026-51302

The CVE-2026-51302 entry concerns SQLite 3.41 with a use-after-free in the expression evaluation logic. The root cause is in sqlite3ReleaseTempReg, which improperly releases temporary register resources, after which exprComputeOperands continues to access the freed memory. This can allow a remote...

CVE-2026-51304

sqlite 3.41 has a use-after-free (UAF) vulnerability in the ORDER BY clause parsing routine. The vendor descriptions state that the code releases memory of an ExprList via sqlite3ExprListDelete(), then accesses the nExpr member of the already freed object, causing invalid memory reads. An attacke...

CVE-2026-51298

CVE-2026-51298 affects SQLite 3.41. The issue is a use-after-free in the JSON extraction function: after releasing a JsonParse object with jsonParseFree(), the code may still access an internal member of the freed pointer, which can cause a service crash and denial of service. The CVE entry lists...

CVE-2026-51297

SQLite 3.41 contains a use-after-free in the JSON parsing logic. Remote attackers can craft a malicious JSON payload to trigger memory free followed by invalid access, potentially leading to arbitrary code execution, sensitive information leakage, and service denial. The sources confirm sqlite 3....
