CVE-2022-48757 – net: fix information leakage in /proc/net/ptype
https://notcve.org/view.php?id=CVE-2022-48757
20 Jun 2024 — 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_sho... • https://git.kernel.org/stable/c/2feb27dbe00cbb4f7d31f90acf6bd0d751dd0a50 • CWE-276: Incorrect Default Permissions •
CVE-2022-48747 – block: Fix wrong offset in bio_truncate()

20 Jun 2024 — 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.

CVE-2022-48740 – selinux: fix double free of cond_list on error paths

20 Jun 2024 — 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.

20 Jun 2024 — 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 ca... • https://git.kernel.org/stable/c/a7de1002135cf94367748ffc695a29812d7633b5 •
CVE-2022-48734 – btrfs: fix deadlock between quota disable and qgroup rescan worker

20 Jun 2024 — In the Linux kernel, the following vulnerability has been resolved: btrfs: fix deadlock between quota disable and qgroup rescan worker Quota disable ioctl starts a transaction before waiting for the qgroup rescan worker completes. However, this wait can be infinite and results in deadlock because of circular dependency among the quota disable ioctl, the qgroup rescan worker and the other task with transaction such as block group relocation task. The deadlock happens with the steps following: 1) Task A calls... • https://git.kernel.org/stable/c/26b3901d20bf9da2c6a00cb1fb48932166f80a45 •

20 Jun 2024 — In the Linux kernel, the following vulnerability has been resolved: btrfs: fix use-after-free after failure to create a snapshot At ioctl.c:create_snapshot(), we allocate a pending snapshot structure and then attach it to the transaction's list of pending snapshots. After that we call btrfs_commit_transaction(), and if that returns an error we jump to 'fail' label, where we kfree() the pending snapshot structure. This can result in a later use-after-free of the pending snapshot: 1) We allocated the pending ... • https://git.kernel.org/stable/c/7e4c72dbaf62f8978af8321a24dbd35566d3a78a •
CVE-2022-48731 – mm/kmemleak: avoid scanning potential huge holes
https://notcve.org/view.php?id=CVE-2022-48731
20 Jun 2024 — In the Linux kernel, the following vulnerability has been resolved: mm/kmemleak: avoid scanning potential huge holes When using devm_request_free_mem_region() and devm_memremap_pages() to add ZONE_DEVICE memory, if requested free mem region's end pfn were huge(e.g., 0x400000000), the node_end_pfn() will be also huge (see move_pfn_range_to_zone()). Thus it creates a huge hole between node_start_pfn() and node_end_pfn().
