https://notcve.org/view.php?id=CVE-2021-47207
In the Linux kernel, the following vulnerability has been resolved: ALSA: gus: fix null pointer dereference on pointer block The pointer block return from snd_gf1_dma_next_block could be null, so there is a potential null pointer dereference issue. Fix this by adding a null check before dereference. • https://git.kernel.org/stable/c/3e28e083dcdf03a18a083f8a47b6bb6b1604b5be https://git.kernel.org/stable/c/cb09c760c201f82df83babc92a5ffea0a01807fc https://git.kernel.org/stable/c/542fa721594a02d2aee0370a764d306ef48d030c https://git.kernel.org/stable/c/ab4c1ebc40f699f48346f634d7b72b9c5193f315 https://git.kernel.org/stable/c/c6d2cefdd05c4810c416fb8d384b5c377bd977bc https://git.kernel.org/stable/c/1ac6cd87d8ddd36c43620f82c4d65b058f725f0f https://git.kernel.org/stable/c/16721797dcef2c7c030ffe73a07f39a65f9323c3 https://git.kernel.org/stable/c/a0d21bb3279476c777434c40d969ea88c •

CVSS: -EPSS: 0%CPEs: 2EXPL: 0CVE-2021-47205 – clk: sunxi-ng: Unregister clocks/resets when unbinding
https://notcve.org/view.php?id=CVE-2021-47205
In the Linux kernel, the following vulnerability has been resolved: clk: sunxi-ng: Unregister clocks/resets when unbinding Currently, unbinding a CCU driver unmaps the device's MMIO region, while leaving its clocks/resets and their providers registered. This can cause a page fault later when some clock operation tries to perform MMIO. Fix this by separating the CCU initialization from the memory allocation, and then using a devres callback to unregister the clocks and resets. This also fixes a memory leak of the `struct ccu_reset`, and uses the correct owner (the specific platform driver) for the clocks and resets. Early OF clock providers are never unregistered, and limited error handling is possible, so they are mostly unchanged. The error reporting is made more consistent by moving the message inside of_sunxi_ccu_probe. • https://git.kernel.org/stable/c/b5dd513daa70ee8f6d281a20bd28485ee9bb7db2 https://git.kernel.org/stable/c/9bec2b9c6134052994115d2d3374e96f2ccb9b9d •

https://notcve.org/view.php?id=CVE-2021-47203
In the Linux kernel, the following vulnerability has been resolved: scsi: lpfc: Fix list_add() corruption in lpfc_drain_txq() When parsing the txq list in lpfc_drain_txq(), the driver attempts to pass the requests to the adapter. If such an attempt fails, a local "fail_msg" string is set and a log message output. The job is then added to a completions list for cancellation. Processing of any further jobs from the txq list continues, but since "fail_msg" remains set, jobs are added to the completions list regardless of whether a wqe was passed to the adapter. If successfully added to txcmplq, jobs are added to both lists resulting in list corruption. Fix by clearing the fail_msg string after adding a job to the completions list. This stops the subsequent jobs from being added to the completions list unless they had an appropriate failure. • https://git.kernel.org/stable/c/ad4776b5eb2e58af1226847fcd3b4f6d051674dd https://git.kernel.org/stable/c/ec70d80a8642900086447ba0cdc79e3f44d42e8f https://git.kernel.org/stable/c/f05a0191b90156e539cccc189b9d87ca2a4d9305 https://git.kernel.org/stable/c/b291d147d0268e93ad866f8bc820ea14497abc9b https://git.kernel.org/stable/c/16bcbfb56d759c25665f786e33ec633b9508a08f https://git.kernel.org/stable/c/c097bd5a59162156d9c2077a2f58732ffbaa9fca https://git.kernel.org/stable/c/814d3610c4ce86e8cf285b2cdac0057a42e82de5 https://git.kernel.org/stable/c/99154581b05c8fb22607afb7c3d66c1ba • CWE-20: Improper Input Validation •
