[PATCH OLK-6.6 0/6] Script execution control
by Gu Bowen 13 Nov '24

13 Nov '24

Ensure that direct file execution (e.g. ./script.sh) and indirect file execution (e.g. sh script.sh) lead to the same result to support script protection. Gu Bowen (2): IMA support script execution check fix kabi breakage due to exec is_check Kees Cook (1): exec: Check __FMODE_EXEC instead of in_execve for LSMs Linus Torvalds (2): execve: open the executable file before doing anything else uselib: remove use of __FMODE_EXEC Mickaël Salaün (1): exec: Add a new AT_CHECK flag to execveat(2) V2: Add a new patch to fix kabi breakage. Align with the original variables to prevent others from inserting new variables before is_check in the future. V3: Add a mainline patch to fix commit 4759ff71f23e(exec: __FMODE_EXEC instead of in_execve for LSMs). V4: Since openEuler has a more standardised way of using KABI_FILL_HOLE to fix kabi breakage, replace it. fs/exec.c | 89 ++++++++++++++++++------------- include/linux/binfmts.h | 5 ++ include/linux/ima.h | 1 + include/uapi/linux/fcntl.h | 31 +++++++++++ kernel/audit.h | 1 + kernel/auditsc.c | 1 + security/apparmor/lsm.c | 4 +- security/integrity/ima/ima_main.c | 11 ++++ security/security.c | 17 +++++- security/tomoyo/tomoyo.c | 3 +- 10 files changed, 123 insertions(+), 40 deletions(-) -- 2.25.1

[PATCH OLK-5.10] iio: light: veml6030: fix IIO device retrieval from embedded device
by Luo Gengkun 13 Nov '24

From: Javier Carrasco <javier.carrasco.cruz(a)gmail.com> stable inclusion from stable-v5.10.228 commit bf3ab8e1c28f10df0823d4ff312f83c952b06a15 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IB2YWA CVE: CVE-2024-50198 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit c7c44e57750c31de43906d97813273fdffcf7d02 upstream. The dev pointer that is received as an argument in the in_illuminance_period_available_show function references the device embedded in the IIO device, not in the i2c client. dev_to_iio_dev() must be used to accessthe right data. The current implementation leads to a segmentation fault on every attempt to read the attribute because indio_dev gets a NULL assignment. This bug has been present since the first appearance of the driver, apparently since the last version (V6) before getting applied. A constant attribute was used until then, and the last modifications might have not been tested again.
