Summary
kernel security update
Details

The Linux Kernel, the operating system core itself.

Security Fix(es):

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

mmc: sdhci-pci: Fix possible memory leak caused by missing pci_dev_put()

pci_get_device() will increase the reference count for the returned pci_dev. We need to use pci_dev_put() to decrease the reference count before amd_probe() returns. There is no problem for the 'smbus_dev == NULL' branch because pci_dev_put() can also handle the NULL input parameter case.(CVE-2022-49787)

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

media: dw2102: Fix null-ptr-deref in dw2102_i2c_transfer()

In dw2102_i2c_transfer, msg is controlled by user. When msg[i].buf is null and msg[i].len is zero, former checks on msg[i].buf would be passed. Malicious data finally reach dw2102_i2c_transfer. If accessing msg[i].buf[0] without sanity check, null ptr deref would happen. We add check on msg[i].len to prevent crash.

Similar commit: commit 950e252cb469 ("[media] dw2102: limit messages to buffer size")(CVE-2023-53146)

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

fs/jfs: Prevent integer overflow in AG size calculation

The JFS filesystem calculates allocation group (AG) size using 1 << l2agsize in dbExtendFS(). When l2agsize exceeds 31 (possible with >2TB aggregates on 32-bit systems), this 32-bit shift operation causes undefined behavior and improper AG sizing.

On 32-bit architectures:

  • Left-shifting 1 by 32+ bits results in 0 due to integer overflow
  • This creates invalid AG sizes (0 or garbage values) in sbi->bmap->db_agsize
  • Subsequent block allocations would reference invalid AG structures
  • Could lead to:
    • Filesystem corruption during extend operations
    • Kernel crashes due to invalid memory accesses
    • Security vulnerabilities via malformed on-disk structures

Fix by casting to s64 before shifting: bmp->db_agsize = (s64)1 << l2agsize;

This ensures 64-bit arithmetic even on 32-bit architectures. The cast matches the data type of db_agsize (s64) and follows similar patterns in JFS block calculation code.

Found by Linux Verification Center (linuxtesting.org) with SVACE.(CVE-2025-37858)
