kernel: Linux kernel: integer overflow and information disclosure via undefined shift operation in drm/amdkfd

A flaw was found in the Linux kernel’s AMD Kernel Fusion Driver amdkfd within the drm subsystem. When either getnumsdmaqueues or getnumxgmisdmaqueues returned 0, the driver performed a bit shift where the number of bits shifted equaled the operand width. Such a shift is undefined behavior in C an...

kernel: kernel: Privilege escalation or denial of service via use-after-free in nf_tables_addchain()

A flaw was found in the Linux kernel. A local attacker with CAPNETADMIN capabilities, or remote packet traffic, could exploit a use-after-free vulnerability in the nftablesaddchain function's error handling. Successful exploitation could lead to a kernel crash, resulting in a Denial of Service Do...

kernel: Linux kernel (qla2xxx): Double free vulnerability leads to denial of service and potential privilege escalation.

A flaw was found in the Linux kernel's qla2xxx block SCSI generic bsg interface. This vulnerability, a double free, occurs because certain vendor-specific handlers incorrectly call the bsgjobdone function on both successful and failed operation paths. A local user could exploit this to trigger...
