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

dm crypt: add cond_resched() to dmcrypt_write()

The loop in dmcrypt_write may be running for unbounded amount of time, thus we need cond_resched() in it.

This commit fixes the following warning:

OESA-2025-1626 — kernel security update

Affected: openEuler:20.03-LTS-SP4: kernel

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

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

scsi: target: Fix WRITE_SAME No Data Buffer crash

In newer version of the SBC specs, we have a NDOB bit that indicates there is no data buffer that gets written out. If this bit is set using commands like "sg_write_same --ndob" we will crash in target_core_iblock/file's execute_write_same handlers when we go to access the se_cmd->t_data_sg because its NULL.

This patch adds a check for the NDOB bit in the common WRITE SAME code because we don't support it. And, it adds a check for zero SG elements in each handler in case the initiator tries to send a normal WRITE SAME with no data buffer.(CVE-2022-21546)

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

capabilities: fix undefined behavior in bit shift for CAP_TO_MASK

Shifting signed 32-bit value by 31 bits is undefined, so changing significant bit to unsigned. The UBSAN warning calltrace like below:
