Affected: Alpaquita:23: linux-lts, Alpaquita:25: linux-lts, Alpaquita:stream: linux-lts

Rejected reason: This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.

In the Linux kernel, the following vulnerability has been resolved:

hwmon: (ibmpex) fix use-after-free in high/low store

The ibmpex_high_low_store() function retrieves driver data using dev_get_drvdata() and uses it without validation. This creates a race condition where the sysfs callback can be invoked after the data structure is freed, leading to use-after-free.

Fix by adding a NULL check after dev_get_drvdata(), and reordering operations in the deletion path to prevent TOCTOU.

Affected: openEuler:22.03-LTS-SP4: kernel

The Linux Kernel, the operating system core itself. Security Fix(es):

In the Linux kernel, the following vulnerability has been resolved:

iomap: Fix possible overflow condition in iomap_write_delalloc_scan

folio_next_index() returns an unsigned long value which left shifted by PAGE_SHIFT could possibly cause an overflow on 32-bit system. Instead use folio_pos(folio) + folio_size(folio), which does this correctly.(CVE-2023-54285)

In the Linux kernel, the following vulnerability has been resolved:
