https://notcve.org/view.php?id=CVE-2022-48757
In the Linux kernel, the following vulnerability has been resolved: net: fix information leakage in /proc/net/ptype In one net namespace, after creating a packet socket without binding it to a device, users in other net namespaces can observe the new `packet_type` added by this packet socket by reading `/proc/net/ptype` file. This is minor information leakage as packet socket is namespace aware. Add a net pointer in `packet_type` to keep the net namespace of of corresponding packet socket. In `ptype_seq_show`, this net pointer must be checked when it is not NULL. • https://git.kernel.org/stable/c/2feb27dbe00cbb4f7d31f90acf6bd0d751dd0a50 https://git.kernel.org/stable/c/8f88c78d24f6f346919007cd459fd7e51a8c7779 https://git.kernel.org/stable/c/be1ca30331c7923c6f376610c1bd6059be9b1908 https://git.kernel.org/stable/c/c38023032a598ec6263e008d62c7f02def72d5c7 https://git.kernel.org/stable/c/b67ad6170c0ea87391bb253f35d1f78857736e54 https://git.kernel.org/stable/c/e372ecd455b6ebc7720f52bf4b5f5d44d02f2092 https://git.kernel.org/stable/c/db044d97460ea792110eb8b971e82569ded536c6 https://git.kernel.org/stable/c/e43669c77cb3a742b7d84ecdc7c68c416 • CWE-276: Incorrect Default Permissions •
CVSS: 7.5EPSS: 0%CPEs: 5EXPL: 0CVE-2022-48747 – block: Fix wrong offset in bio_truncate()
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 •

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.
