CVE-2023-53244

In Linux kernel, the media: pci: tw68 driver vulnerability CVE-2023-53244 fixes a null pointer dereference in buffer handling: if dma_alloc_coherent fails during tw68_risc_buffer(), buf->cpu may be null and later accesses/free could crash. The fix adds checks on the return value of tw68_risc_b...

CVE-2022-50295

CVE-2022-50295: In the Linux kernel io_uring/msg_ring path, a NULL pointer dereference occurs in io_msg_send_fd() when file_ptr is NULL, causing src_file to be NULL and get_file() to dereference a NULL pointer and trigger a crash. The issue was fixed by adding a NULL check in io_msg_send_fd(), pr...

CVE-2023-53240

The CVE-2023-53240 issue concerns the Linux kernel’s xsk path. If a napi id is marked on an interface not brought up, xsk_sendmsg /xsk_poll can call xsk_xmit(), which may dereference a NULL pointers to xs->dev when IFF_UP is not set, causing a kernel NULL pointer dereference. The fix restructu...

CVE-2023-53240 xsk: check IFF_UP earlier in Tx path

In the Linux kernel, the following vulnerability has been resolved: xsk: check IFFUP earlier in Tx path Xsk Tx can be triggered via either sendmsg or poll syscalls. These two paths share a call to common function xskxmit which has two sanity checks within. A pseudo code example to show the two...
