CVE-2022-49191

Concrete details found: CVE-2022-49191 affects the Linux kernel mxser code path, where xmit_buf leaks in activate() when LSR == 0xff and ->shutdown() is not called on failure, leaving the buffer unfreed. The fix adds a proper free path to a designated label and ensures the code jumps there fro...

CVE-2022-49246

CVE-2022-49246 affects the Linux kernel, specifically ASoC: atmel: snd_proto_probe. The issue is a refcount leak: of_parse_phandle() returns a device_node with refcount incremented, but of_node_put() was only called in the regular path, not in error paths. The fix ensures of_node_put() is called ...

CVE-2022-49270

CVE-2022-49270 : In the Linux kernel, a use-after-free can occur in dm_cleanup_zoned_dev() if it is not called before blk_cleanup_disk() proceeds through its cleanup path (blk_cleanup_disk->blk_cleanup_queue()->kobject_put()->blk_release_queue()->…->blk_free_queue_rcu()). This raci...
