CVE-2023-53449

CVE-2023-53449 affects the Linux kernel in the s390/dasd area. The root cause was a potential memory leak in dasd_eckd_init() where dasd_reserve_req was allocated before dasd_vol_info_req and could not be freed on error. The fix ensures dasd_reserve_req is freed before error returns, matching the...

CVE-2022-50425

CVE-2022-50425 is a Linux kernel vulnerability in the x86/fpu path. The issue occurs in copy_xstate_to_uabi() when an extended state component exists in init_fpstate but not fpstate, causing a NULL pointer dereference during XSAVE state handling in KVM/KVM-related ioctl paths. The mitigation desc...
