https://notcve.org/view.php?id=CVE-2024-41089
In the Linux kernel, the following vulnerability has been resolved: drm/nouveau/dispnv04: fix null pointer dereference in nv17_tv_get_hd_modes In nv17_tv_get_hd_modes(), the return value of drm_mode_duplicate() is assigned to mode, which will lead to a possible NULL pointer dereference on failure of drm_mode_duplicate(). The same applies to drm_cvt_mode(). Add a check to avoid null pointer dereference. • https://git.kernel.org/stable/c/ffabad4aa91e33ced3c6ae793fb37771b3e9cb51 https://git.kernel.org/stable/c/1c9f2e60150b4f13789064370e37f39e6e060f50 https://git.kernel.org/stable/c/56fc4d3b0bdef691831cd95715a7ca3ebea98b2d https://git.kernel.org/stable/c/5eecb49a6c268dc229005bf6e8167d4001dc09a0 https://git.kernel.org/stable/c/30cbf6ffafbbdd8a6e4e5f0a2e9a9827ee83f3ad https://git.kernel.org/stable/c/7ece609b0ce7a7ea8acdf512a77d1fee26621637 https://git.kernel.org/stable/c/6e49a157d541e7e97b815a56f4bdfcbc89844a59 https://git.kernel.org/stable/c/6d411c8ccc0137a612e0044489030a194 • CWE-476: NULL Pointer Dereference •
CVSS: -EPSS: 0%CPEs: 4EXPL: 0CVE-2024-41088 – can: mcp251xfd: fix infinite loop when xmit fails
https://notcve.org/view.php?id=CVE-2024-41088
In the Linux kernel, the following vulnerability has been resolved: can: mcp251xfd: fix infinite loop when xmit fails When the mcp251xfd_start_xmit() function fails, the driver stops processing messages, and the interrupt routine does not return, running indefinitely even after killing the running application. Error messages: [ 441.298819] mcp251xfd spi2.0 can0: ERROR in mcp251xfd_start_xmit: -16 [ 441.306498] mcp251xfd spi2.0 can0: Transmit Event FIFO buffer not empty. (seq=0x000017c7, tef_tail=0x000017cf, tef_head=0x000017d0, tx_head=0x000017d3). ... and repeat forever. The issue can be triggered when multiple devices share the same SPI interface. And there is concurrent access to the bus. The problem occurs because tx_ring->head increments even if mcp251xfd_start_xmit() fails. Consequently, the driver skips one TX package while still expecting a response in mcp251xfd_handle_tefif_one(). Resolve the issue by starting a workqueue to write the tx obj synchronously if err = -EBUSY. In case of another error, decrement tx_ring->head, remove skb from the echo stack, and drop the message.

In the Linux kernel, the following vulnerability has been resolved: ata: libata-core: Fix double free on error If e.g. the ata_port_alloc() call in ata_host_alloc() fails, we will jump to the err_out label, which will call devres_release_group(). devres_release_group() will trigger a call to ata_host_release(). ata_host_release() calls kfree(host), so executing the kfree(host) in ata_host_alloc() will lead to a double free: kernel BUG at mm/slub.c:553!
