https://notcve.org/view.php?id=CVE-2023-52749
In the Linux kernel, the following vulnerability has been resolved: spi: Fix null dereference on suspend A race condition exists where a synchronous (noqueue) transfer can be active during a system suspend. This can cause a null pointer dereference exception to occur when the system resumes. Example order of events leading to the exception: 1. spi_sync() calls __spi_transfer_message_noqueue() which sets ctlr->cur_msg 2. Spi transfer begins via spi_transfer_one_message() 3. System is suspended interrupting the transfer context 4. System is resumed 6. spi_controller_resume() calls spi_start_queue() which resets cur_msg to NULL 7. • https://git.kernel.org/stable/c/4ec4508db97502a12daee88c74782e8d35ced068 https://git.kernel.org/stable/c/96474ea47dc67b0704392d59192b233c8197db0e https://git.kernel.org/stable/c/bef4a48f4ef798c4feddf045d49e53c8a97d5e37 https://access.redhat.com/security/cve/CVE-2023-52749 https://bugzilla.redhat.com/show_bug.cgi?id=2282679 • CWE-476: NULL Pointer Dereference •

In the Linux kernel, the following vulnerability has been resolved: f2fs: avoid format-overflow warning With gcc and W=1 option, there's a warning like this: fs/f2fs/compress.c: In function ‘f2fs_init_page_array_cache’: fs/f2fs/compress.c:1984:47: error: ‘%u’ directive writing between 1 and 7 bytes into a region of size between 5 and 8 [-Werror=format-overflow=] 1984 | sprintf(slab_name, "f2fs_page_array_entry-%u:%u", MAJOR(dev), MINOR(dev)); | ^~ String "f2fs_page_array_entry-%u:%u" can up to 35. The first "%u" can up to 4 and the second "%u" can up to 7, so total size is "24 + 4 + 7 = 35". slab_name's size should be 35 rather than 32. En el kernel de Linux se ha resuelto la siguiente vulnerabilidad: f2fs: evitar aviso de desbordamiento de formato. Con la opción gcc y W=1, aparece un aviso como este: fs/f2fs/compress.c: En la función 'f2fs_init_page_array_cache': fs/f2fs /compress.c:1984:47: error: directiva '%u' escribiendo entre 1 y 7 bytes en una región de tamaño entre 5 y 8 [-Werror=format-overflow=] 1984 | sprintf(slab_name, "f2fs_page_array_entry-%u:%u", MAJOR(dev), MINOR(dev)); | ^~ La cadena "f2fs_page_array_entry-%u:%u" puede tener hasta 35.

In the Linux kernel, the following vulnerability has been resolved: drm/radeon: fix a possible null pointer dereference In radeon_fp_native_mode(), the return value of drm_mode_duplicate() is assigned to mode, which will lead to a NULL pointer dereference on failure of drm_mode_duplicate(). Add a check to avoid npd. The failure status of drm_cvt_mode() on the other path is checked too. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/radeon: corrige una posible desreferencia del puntero null. En radeon_fp_native_mode(), el valor de retorno de drm_mode_duplicate() se asigna al modo, lo que conducirá a una desreferencia del puntero NULL en caso de falla de drm_mode_duplicate().
