kernel: "Fragnesia" is a variant of Dirty Frag vulnerability in the ESP/XFRM leading to Local Privilege Escalation (LPE) vulnerability in the Linux kernel

A flaw was found in the Linux kernel's XFRM ESP-in-TCP subsystem. Unsafe in-place cryptographic processing allows a low-privileged local attacker to write arbitrary bytes into the page cache of read-only files, including sensitive system files. An attacker can exploit this to overwrite privileged...

kernel: Linux kernel: Denial of service and memory corruption in RDMA umad

A flaw was found in the Linux kernel's Remote Direct Memory Access RDMA umad User Mode Access Device component. A local user can exploit this vulnerability by manipulating input, causing an integer underflow that leads to an out-of-bounds memory write. This memory corruption can result in a denia...

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...

kernel: Read root-owned files as an unprivileged user

A vulnerability was found in the Linux kernel that allows an unprivileged local user to read sensitive files normally restricted to the root user. The flaw occurs during process exit, where a brief window allows an attacker to intercept file access from a privileged process before it fully...

kernel: proc: fix UAF in proc_get_inode()

In the Linux kernel, the following vulnerability has been resolved: proc: fix UAF in procgetinode Fix race between rmmod and /proc/XXX's inode instantiation. The bug is that pde-procops don't belong to /proc, it belongs to a module, therefore dereferencing it after /proc entry has been registered...
