[PATCH OLK-5.10] gpiolib: fix memory use-after-free in gpiochip_setup_dev()
by He Yujie 16 Dec '24

16 Dec '24

hulk inclusion category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IB8UN5 -------------------------------- Commit aa1e2bfdc899 attempt to fix a CVE problem, but the patch conflicted with current version. When the patch is adapted, an error is introduced in the function of gpiochip_add_data_with_key. After the gdev is released, the gdev is still accessed, resulting in use-after-free. The value of gdev->ngpio is assigned from gc->ngpio and is not changed during the processing of function. Therefore, this patch changes gdev->ngpio to gc->ngpio to solve the above use-after-free problem.

[PATCH openEuler-1.0-LTS] nilfs2: fix null-ptr-deref in block_touch_buffer tracepoint
by He Yujie 16 Dec '24

From: Ryusuke Konishi <konishi.ryusuke(a)gmail.com> stable inclusion from stable-v4.19.325 commit 085556bf8c70e2629e02e79268dac3016a08b8bf category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IB956P CVE: CVE-2024-53131 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit cd45e963e44b0f10d90b9e6c0e8b4f47f3c92471 upstream. Patch series "nilfs2: fix null-ptr-deref bugs on block tracepoints". This series fixes null pointer dereference bugs that occur when using nilfs2 and two block-related tracepoints. This patch (of 2): It has been reported that when using "block:block_touch_buffer" tracepoint, touch_buffer() called from __nilfs_get_folio_block() causes a NULL pointer dereference, or a general protection fault when KASAN is enabled. This happens because since the tracepoint was added in touch_buffer(), it references the dev_t member bh->b_bdev->bd_dev regardless of whether the buffer head has a pointer to a block_device structure. In the current implementation, the block_device structure is set after the function returns to the caller. Here, touch_buffer() is used to mark the folio/page that owns the buffer head as accessed, but the common search helper for folio/page used by the caller function was optimized to mark the folio/page as accessed when it was reimplemented a long time ago, eliminating the need to call touch_buffer() here in the first place. So this solves the issue by eliminating the touch_buffer() call itself.
