https://notcve.org/view.php?id=CVE-2024-49854
In the Linux kernel, the following vulnerability has been resolved: block, bfq: fix uaf for accessing waker_bfqq after splitting After commit 42c306ed7233 ("block, bfq: don't break merge chain in bfq_split_bfqq()"), if the current procress is the last holder of bfqq, the bfqq can be freed after bfq_split_bfqq(). Hence recored the bfqq and then access bfqq->waker_bfqq may trigger UAF. What's more, the waker_bfqq may in the merge chain of bfqq, hence just recored waker_bfqq is still not safe. Fix the problem by adding a helper bfq_waker_bfqq() to check if bfqq->waker_bfqq is in the merge chain, and current procress is the only holder. • https://git.kernel.org/stable/c/9e813033594b141f61ff0ef0cfaaef292564b041 https://git.kernel.org/stable/c/3a5f45a4ad4e1fd36b0a998eef03d76a4f02a2a8 https://git.kernel.org/stable/c/3630a18846c7853aa326d3b42fd0a855af7b41bc https://git.kernel.org/stable/c/63a07379fdb6c72450cb05294461c6016b8b7726 https://git.kernel.org/stable/c/de0456460f2abf921e356ed2bd8da87a376680bd https://git.kernel.org/stable/c/0780451f03bf518bc032a7c584de8f92e2d39d7f https://git.kernel.org/stable/c/0b8bda0ff17156cd3f60944527c9d8c9f99f1583 https://git.kernel.org/stable/c/cae58d19121a70329cf971359e2518c93 •
CVSS: -EPSS: 0%CPEs: 8EXPL: 0CVE-2024-49851 – tpm: Clean up TPM space after command failure
https://notcve.org/view.php?id=CVE-2024-49851
In the Linux kernel, the following vulnerability has been resolved: tpm: Clean up TPM space after command failure tpm_dev_transmit prepares the TPM space before attempting command transmission. However if the command fails no rollback of this preparation is done. This can result in transient handles being leaked if the device is subsequently closed with no further commands performed. Fix this by flushing the space in the event of command transmission failure. • https://git.kernel.org/stable/c/745b361e989af21ad40811c2586b60229f870a68 https://git.kernel.org/stable/c/87e8134c18977b566f4ec248c8a147244da69402 https://git.kernel.org/stable/c/2c9b228938e9266a1065a3f4fe5c99b7235dc439 https://git.kernel.org/stable/c/ebc4e1f4492d114f9693950621b3ea42b2f82bec https://git.kernel.org/stable/c/c84ceb546f30432fccea4891163f7050f5bee5dd https://git.kernel.org/stable/c/82478cb8a23bd4f97935bbe60d64528c6d9918b4 https://git.kernel.org/stable/c/adf4ce162561222338cf2c9a2caa294527f7f721 https://git.kernel.org/stable/c/3f9f72d843c92fb6f4ff7460d774413cd •

https://notcve.org/view.php?id=CVE-2024-47757
In the Linux kernel, the following vulnerability has been resolved: nilfs2: fix potential oob read in nilfs_btree_check_delete() The function nilfs_btree_check_delete(), which checks whether degeneration to direct mapping occurs before deleting a b-tree entry, causes memory access outside the block buffer when retrieving the maximum key if the root node has no entries. This does not usually happen because b-tree mappings with 0 child nodes are never created by mkfs.nilfs2 or nilfs2 itself. However, it can happen if the b-tree root node read from a device is configured that way, so fix this potential issue by adding a check for that case. • https://git.kernel.org/stable/c/17c76b0104e4a6513983777e1a17e0297a12b0c4 https://git.kernel.org/stable/c/f3a9859767c7aea758976f5523903d247e585129 https://git.kernel.org/stable/c/ed76d381dae125b81d09934e365391a656249da8 https://git.kernel.org/stable/c/d20674f31626e0596ae4c1d9401dfb6739b81b58 https://git.kernel.org/stable/c/c4f8554996e8ada3be872dfb8f60e93bcf15fb27 https://git.kernel.org/stable/c/a8abfda768b9f33630cfbc4af6c4214f1e5681b0 https://git.kernel.org/stable/c/257f9e5185eb6de83377caea686c306e22e871f2 https://git.kernel.org/stable/c/a33e967b681e088a125b979975c93e345 •

In the Linux kernel, the following vulnerability has been resolved: PCI: keystone: Fix if-statement expression in ks_pcie_quirk() This code accidentally uses && where || was intended. It potentially results in a NULL dereference. Thus, fix the if-statement expression to use the correct condition.

https://notcve.org/view.php?id=CVE-2024-47749
In the Linux kernel, the following vulnerability has been resolved: RDMA/cxgb4: Added NULL check for lookup_atid The lookup_atid() function can return NULL if the ATID is invalid or does not exist in the identifier table, which could lead to dereferencing a null pointer without a check in the `act_establish()` and `act_open_rpl()` functions. Add a NULL check to prevent null pointer dereferencing.
