UBUNTU-CVE-2024-41065

In the Linux kernel, the following vulnerability has been resolved: powerpc/pseries: Whitelist dtl slub object for copying to userspace Reading the dispatch trace log from /sys/kernel/debug/powerpc/dtl/cpu- results in a BUG when the config CONFIGHARDENEDUSERCOPY is enabled as shown below. kernel...

CVE-2024-41065

The CVE-2024-41065 issue is in the Linux kernel’s powerpc/pseries code related to usercopy hardening. When CONFIG_HARDENED_USERCOPY is enabled, reading the dispatch log from /sys/kernel/debug/powerpc/dtl/cpu-* could trigger a kernel BUG in usercopy (mm/usercopy.c). The root cause involves copying...

CVE-2022-48821

In CVE-2022-48821, the Linux kernel misc/fastrpc path fixes a use-after-free: if FASTRPC_IOCTL_ALLOC_DMA_BUFF copy-back to userland fails, the code previously called dma_buf_put() on a buffer no longer owned, risking a stale fd entry. The remediation avoids dma_buf_put() in that failure path and ...

CVE-2022-48771

The CVE-2022-48771 issue affects the Linux kernel drm/vmwgfx: a failing usercopy of the fence_rep object can leave a stale file descriptor entry because put_unused_fd() isn’t released; this can let userland reference a dangling file descriptor and enable use-after-free scenarios. The fix defers t...
