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 •

In the Linux kernel, the following vulnerability has been resolved: drm/msm/dsi: invalid parameter check in msm_dsi_phy_enable The function performs a check on the "phy" input parameter, however, it is used before the check. Initialize the "dev" variable after the sanity check to avoid a possible NULL pointer dereference.

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: net: amd-xgbe: Fix skb data length underflow There will be BUG_ON() triggered in include/linux/skbuff.h leading to intermittent kernel panic, when the skb length underflow is detected. Fix this by dropping the packet if such length underflows are seen because of inconsistencies in the hardware descriptors. • https://git.kernel.org/stable/c/fafc9555d87a19c78bcd43ed731c3a73bf0b37a9 https://git.kernel.org/stable/c/622c36f143fc9566ba49d7cec994c2da1182d9e2 https://git.kernel.org/stable/c/ae43f9360a21b35cf785ae9a0fdce524d7af0938 https://git.kernel.org/stable/c/ae9d577f3dbb686862b7d0dc9cc73054f0964d4d https://git.kernel.org/stable/c/9924c80bd484340191e586110ca22bff23a49f2e https://git.kernel.org/stable/c/617f9934bb37993b9813832516f318ba874bcb7d https://git.kernel.org/stable/c/34aeb4da20f93ac80a6291a2dbe7b9c6460e9b26 https://git.kernel.org/stable/c/9892742f035f7aa7dcd2bb0750effa486 • CWE-124: Buffer Underwrite ('Buffer Underflow') •

In the Linux kernel, the following vulnerability has been resolved: rtnetlink: make sure to refresh master_dev/m_ops in __rtnl_newlink() While looking at one unrelated syzbot bug, I found the replay logic in __rtnl_newlink() to potentially trigger use-after-free.
