https://notcve.org/view.php?id=CVE-2024-50160
In the Linux kernel, the following vulnerability has been resolved: ALSA: hda/cs8409: Fix possible NULL dereference If snd_hda_gen_add_kctl fails to allocate memory and returns NULL, then NULL pointer dereference will occur in the next line. Since dolphin_fixups function is a hda_fixup function which is not supposed to return any errors, add simple check before dereference, ignore the fail. Found by Linux Verification Center (linuxtesting.org) with SVACE. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ALSA: hda/cs8409: Se corrige una posible desreferencia de NULL. Si snd_hda_gen_add_kctl no puede asignar memoria y devuelve NULL, se producirá una desreferencia de puntero NULL en la siguiente línea. Dado que la función dolphin_fixups es una función hda_fixup que no debería devolver ningún error, se debe agregar una comprobación simple antes de la desreferencia e ignorar el error. Encontrado por Linux Verification Center (linuxtesting.org) con SVACE. • https://git.kernel.org/stable/c/20e507724113300794f16884e7e7507d9b4dec68 https://git.kernel.org/stable/c/4e19aca8db696b6ba4dd8c73657405e15c695f14 https://git.kernel.org/stable/c/21dc97d5086fdabbe278786bb0a03cbf2e26c793 https://git.kernel.org/stable/c/8971fd61210d75fd2af225621cd2fcc87eb1847c https://git.kernel.org/stable/c/a5dd71a8b849626f42d08a5e73d382f2016fc7bc https://git.kernel.org/stable/c/c9bd4a82b4ed32c6d1c90500a52063e6e341517f •

https://notcve.org/view.php?id=CVE-2024-50158
In the Linux kernel, the following vulnerability has been resolved: RDMA/bnxt_re: Fix out of bound check Driver exports pacing stats only on GenP5 and P7 adapters. But while parsing the pacing stats, driver has a check for "rdev->dbr_pacing". This caused a trace when KASAN is enabled. BUG: KASAN: slab-out-of-bounds in bnxt_re_get_hw_stats+0x2b6a/0x2e00 [bnxt_re] Write of size 8 at addr ffff8885942a6340 by task modprobe/4809 En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: RDMA/bnxt_re: Se ha corregido la comprobación fuera de los límites. El controlador exporta estadísticas de ritmo solo en adaptadores GenP5 y P7. Pero al analizar las estadísticas de ritmo, el controlador tiene una comprobación para "rdev->dbr_pacing". • https://git.kernel.org/stable/c/8b6573ff3420a2da1deb469a480dbc454745f784 https://git.kernel.org/stable/c/05c5fcc1869a08e36a29691699b6534e5a00a82b https://git.kernel.org/stable/c/c11b9b03ea5252898f91f3388c248f0dc47bda52 https://git.kernel.org/stable/c/a9e6e7443922ac0a48243c35d03834c96926bff1 •
CVSS: -EPSS: 0%CPEs: 2EXPL: 0CVE-2024-50157 – RDMA/bnxt_re: Avoid CPU lockups due fifo occupancy check loop
https://notcve.org/view.php?id=CVE-2024-50157
In the Linux kernel, the following vulnerability has been resolved: RDMA/bnxt_re: Avoid CPU lockups due fifo occupancy check loop Driver waits indefinitely for the fifo occupancy to go below a threshold as soon as the pacing interrupt is received. This can cause soft lockup on one of the processors, if the rate of DB is very high. Add a loop count for FPGA and exit the __wait_for_fifo_occupancy_below_th if the loop is taking more time. Pacing will be continuing until the occupancy is below the threshold. This is ensured by the checks in bnxt_re_pacing_timer_exp and further scheduling the work for pacing based on the fifo occupancy. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: RDMA/bnxt_re: Evitar bloqueos de CPU debido al bucle de comprobación de ocupación fifo El controlador espera indefinidamente a que la ocupación fifo baje de un umbral tan pronto como se recibe la interrupción de ritmo. • https://git.kernel.org/stable/c/2ad4e6303a6d7518632739eaf67821a3553db1bd https://git.kernel.org/stable/c/2fb6b2e82413e401b72dfeacd7a60416fcfc5b41 https://git.kernel.org/stable/c/8be3e5b0c96beeefe9d5486b96575d104d3e7d17 •
CVSS: -EPSS: 0%CPEs: 5EXPL: 0CVE-2024-50156 – drm/msm: Avoid NULL dereference in msm_disp_state_print_regs()
https://notcve.org/view.php?id=CVE-2024-50156
In the Linux kernel, the following vulnerability has been resolved: drm/msm: Avoid NULL dereference in msm_disp_state_print_regs() If the allocation in msm_disp_state_dump_regs() failed then `block->state` can be NULL. The msm_disp_state_print_regs() function _does_ have code to try to handle it with: if (*reg) dump_addr = *reg; ...but since "dump_addr" is initialized to NULL the above is actually a noop. The code then goes on to dereference `dump_addr`. Make the function print "Registers not stored" when it sees a NULL to solve this. Since we're touching the code, fix msm_disp_state_print_regs() not to pointlessly take a double-pointer and properly mark the pointer as `const`. Patchwork: https://patchwork.freedesktop.org/patch/619657/ En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/msm: Evitar la desreferenciación NULL en msm_disp_state_print_regs() Si la asignación en msm_disp_state_dump_regs() falla, entonces `block->state` puede ser NULL. La función msm_disp_state_print_regs() _sí_ tiene código para intentar manejarlo con: if (*reg) dump_addr = *reg; ...pero como "dump_addr" se inicializa a NULL, lo anterior es en realidad un noop. • https://git.kernel.org/stable/c/98659487b845c05b6bed85d881713545db674c7c https://git.kernel.org/stable/c/42cf045086feae77b212f0f66e742b91a5b566b7 https://git.kernel.org/stable/c/e8e9f2a12a6214080c8ea83220a596f6e1dedc6c https://git.kernel.org/stable/c/f7ad916273483748582d97cfa31054ccb19224f3 https://git.kernel.org/stable/c/563aa81fd66a4e7e6e551a0e02bcc23957cafe2f https://git.kernel.org/stable/c/293f53263266bc4340d777268ab4328a97f041fa •
