https://notcve.org/view.php?id=CVE-2022-48747
In the Linux kernel, the following vulnerability has been resolved: block: Fix wrong offset in bio_truncate() bio_truncate() clears the buffer outside of last block of bdev, however current bio_truncate() is using the wrong offset of page. So it can return the uninitialized data. This happened when both of truncated/corrupted FS and userspace (via bdev) are trying to read the last of bdev. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: bloque: corrige el desplazamiento incorrecto en bio_truncate() bio_truncate() borra el búfer fuera del último bloque de bdev, sin embargo, el bio_truncate() actual está usando el desplazamiento de página incorrecto. Entonces puede devolver los datos no inicializados. Esto sucedió cuando tanto el FS truncado/corrupto como el espacio de usuario (a través de bdev) intentaban leer lo último de bdev. • https://git.kernel.org/stable/c/6cbf4c731d7812518cd857c2cfc3da9fd120f6ae https://git.kernel.org/stable/c/b63e120189fd92aff00096d11e2fc5253f60248b https://git.kernel.org/stable/c/4633a79ff8bc82770486a063a08b55e5162521d8 https://git.kernel.org/stable/c/941d5180c430ce5b0f7a3622ef9b76077bfa3d82 https://git.kernel.org/stable/c/3ee859e384d453d6ac68bfd5971f630d9fa46ad3 https://access.redhat.com/security/cve/CVE-2022-48747 https://bugzilla.redhat.com/show_bug.cgi?id=2293312 • CWE-99: Improper Control of Resource Identifiers ('Resource Injection') CWE-908: Use of Uninitialized Resource •

https://notcve.org/view.php?id=CVE-2022-48740
In the Linux kernel, the following vulnerability has been resolved: selinux: fix double free of cond_list on error paths On error path from cond_read_list() and duplicate_policydb_cond_list() the cond_list_destroy() gets called a second time in caller functions, resulting in NULL pointer deref. Fix this by resetting the cond_list_len to 0 in cond_list_destroy(), making subsequent calls a noop. Also consistently reset the cond_list pointer to NULL after freeing.

https://notcve.org/view.php?id=CVE-2022-48735
In the Linux kernel, the following vulnerability has been resolved: ALSA: hda: Fix UAF of leds class devs at unbinding The LED class devices that are created by HD-audio codec drivers are registered via devm_led_classdev_register() and associated with the HD-audio codec device. Unfortunately, it turned out that the devres release doesn't work for this case; namely, since the codec resource release happens before the devm call chain, it triggers a NULL dereference or a UAF for a stale set_brightness_delay callback. For fixing the bug, this patch changes the LED class device register and unregister in a manual manner without devres, keeping the instances in hda_gen_spec. • https://git.kernel.org/stable/c/a7de1002135cf94367748ffc695a29812d7633b5 https://git.kernel.org/stable/c/0e629052f013eeb61494d4df2f1f647c2a9aef47 https://git.kernel.org/stable/c/813e9f3e06d22e29872d4fd51b54992d89cf66c8 https://git.kernel.org/stable/c/549f8ffc7b2f7561bea7f90930b6c5104318e87b •
