DATE CVE VULNERABILITY TITLE RISK
2024-05-21 CVE-2023-52827 Out-of-bounds Read vulnerability in Linux Kernel
In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: fix possible out-of-bound read in ath12k_htt_pull_ppdu_stats() len is extracted from HTT message and could be an unexpected value in case errors happen, so add validation before using to avoid possible out-of-bound read in the following message iteration and parsing. The same issue also applies to ppdu_info->ppdu_stats.common.num_users, so validate it before using too. These are found during code review. Compile test only.

2024-05-21 CVE-2021-47280 Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in Linux Kernel
In the Linux kernel, the following vulnerability has been resolved: drm: Fix use-after-free read in drm_getunique() There is a time-of-check-to-time-of-use error in drm_getunique() due to retrieving file_priv->master prior to locking the device's master mutex. An example can be seen in the crash report of the use-after-free error found by Syzbot: https://syzkaller.appspot.com/bug?id=148d2f1dfac64af52ffd27b661981a540724f803 In the report, the master pointer was used after being freed.
