In the Linux kernel, the following vulnerability has been resolved: ASoC: max9759: fix underflow in speaker_gain_control_put() Check for negative values of "priv->gain" to prevent an out of bounds access. The concern is that these might come from the user via: -> snd_ctl_elem_write_user() -> snd_ctl_elem_write() -> kctl->put() En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ASoC: max9759: corrige el desbordamiento en altavoz_gain_control_put() Compruebe si hay valores negativos de "priv->gain" para evitar un acceso fuera de los límites.

CVSS: -EPSS: 0%CPEs: 4EXPL: 0CVE-2022-48714 – bpf: Use VM_MAP instead of VM_ALLOC for ringbuf
https://notcve.org/view.php?id=CVE-2022-48714
In the Linux kernel, the following vulnerability has been resolved: bpf: Use VM_MAP instead of VM_ALLOC for ringbuf After commit 2fd3fb0be1d1 ("kasan, vmalloc: unpoison VM_ALLOC pages after mapping"), non-VM_ALLOC mappings will be marked as accessible in __get_vm_area_node() when KASAN is enabled. But now the flag for ringbuf area is VM_ALLOC, so KASAN will complain out-of-bound access after vmap() returns. Because the ringbuf area is created by mapping allocated pages, so use VM_MAP instead. After the change, info in /proc/vmallocinfo also changes from [start]-[end] 24576 ringbuf_map_alloc+0x171/0x290 vmalloc user to [start]-[end] 24576 ringbuf_map_alloc+0x171/0x290 vmap user En el kernel de Linux, se resolvió la siguiente vulnerabilidad: bpf: use VM_MAP en lugar de VM_ALLOC para ringbuf Después del commit 2fd3fb0be1d1 ("kasan, vmalloc: despoisone las páginas VM_ALLOC después del mapeo"), los mapeos que no sean VM_ALLOC se marcarán como accesibles en __get_vm_area_node( ) cuando KASAN está habilitado. Pero ahora el indicador para el área ringbuf es VM_ALLOC, por lo que KASAN se quejará del acceso fuera de los límites después de que regrese vmap(). Debido a que el área ringbuf se crea asignando páginas asignadas, use VM_MAP en su lugar. • https://git.kernel.org/stable/c/457f44363a8894135c85b7a9afd2bd8196db24ab https://git.kernel.org/stable/c/6304a613a97d6dcd49b93fbad31e9f39d1e138d6 https://git.kernel.org/stable/c/5e457aeab52a5947619e1f18047f4d2f3212b3eb https://git.kernel.org/stable/c/d578933f6226d5419af9306746efa1c693cbaf9c https://git.kernel.org/stable/c/b293dcc473d22a62dc6d78de2b15e4f49515db56 •
CVSS: -EPSS: 0%CPEs: 4EXPL: 0CVE-2022-48713 – perf/x86/intel/pt: Fix crash with stop filters in single-range mode
https://notcve.org/view.php?id=CVE-2022-48713
In the Linux kernel, the following vulnerability has been resolved: perf/x86/intel/pt: Fix crash with stop filters in single-range mode Add a check for !buf->single before calling pt_buffer_region_size in a place where a missing check can cause a kernel crash. Fixes a bug introduced by commit 670638477aed ("perf/x86/intel/pt: Opportunistically use single range output mode"), which added a support for PT single-range output mode. Since that commit if a PT stop filter range is hit while tracing, the kernel will crash because of a null pointer dereference in pt_handle_status due to calling pt_buffer_region_size without a ToPA configured. The commit which introduced single-range mode guarded almost all uses of the ToPA buffer variables with checks of the buf->single variable, but missed the case where tracing was stopped by the PT hardware, which happens when execution hits a configured stop filter. Tested that hitting a stop filter while PT recording successfully records a trace with this patch but crashes without this patch. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: perf/x86/intel/pt: soluciona el fallo con filtros de parada en modo de rango único.
