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.

https://notcve.org/view.php?id=CVE-2024-47748
In the Linux kernel, the following vulnerability has been resolved: vhost_vdpa: assign irq bypass producer token correctly We used to call irq_bypass_unregister_producer() in vhost_vdpa_setup_vq_irq() which is problematic as we don't know if the token pointer is still valid or not. Actually, we use the eventfd_ctx as the token so the life cycle of the token should be bound to the VHOST_SET_VRING_CALL instead of vhost_vdpa_setup_vq_irq() which could be called by set_status(). Fixing this by setting up irq bypass producer's token when handling VHOST_SET_VRING_CALL and un-registering the producer before calling vhost_vring_ioctl() to prevent a possible use after free as eventfd could have been released in vhost_vring_ioctl(). And such registering and unregistering will only be done if DRIVER_OK is set. • https://git.kernel.org/stable/c/2cf1ba9a4d15cb78b96ea97f727b93382c3f9a60 https://git.kernel.org/stable/c/0c170b1e918b9afac25e2bbd01eaa2bfc0ece8c0 https://git.kernel.org/stable/c/927a2580208e0f9b0b47b08f1c802b7233a7ba3c https://git.kernel.org/stable/c/ec5f1b54ceb23475049ada6e7a43452cf4df88d1 https://git.kernel.org/stable/c/ca64edd7ae93402af2596a952e0d94d545e2b9c0 https://git.kernel.org/stable/c/fae9b1776f53aab93ab345bdbf653b991aed717d https://git.kernel.org/stable/c/7cf2fb51175cafe01df8c43fa15a06194a59c6e2 https://git.kernel.org/stable/c/02e9e9366fefe461719da5d173385b668 •

https://notcve.org/view.php?id=CVE-2024-47747
In the Linux kernel, the following vulnerability has been resolved: net: seeq: Fix use after free vulnerability in ether3 Driver Due to Race Condition In the ether3_probe function, a timer is initialized with a callback function ether3_ledoff, bound to &prev(dev)->timer. Once the timer is started, there is a risk of a race condition if the module or device is removed, triggering the ether3_remove function to perform cleanup. The sequence of operations that may lead to a UAF bug is as follows: CPU0 CPU1 | ether3_ledoff ether3_remove | free_netdev(dev); | put_devic | kfree(dev); | | ether3_outw(priv(dev)->regs.config2 |= CFG2_CTRLO, REG_CONFIG2); | // use dev Fix it by ensuring that the timer is canceled before proceeding with the cleanup in ether3_remove. • https://git.kernel.org/stable/c/6fd9c53f71862a4797b7ed8a5de80e2c64829f56 https://git.kernel.org/stable/c/25d559ed2beec9b34045886100dac46d1ad92eba https://git.kernel.org/stable/c/b5a84b6c772564c8359a9a0fbaeb2a2944aa1ee9 https://git.kernel.org/stable/c/338a0582b28e69460df03af50e938b86b4206353 https://git.kernel.org/stable/c/822c7bb1f6f8b0331e8d1927151faf8db3b33afd https://git.kernel.org/stable/c/1c57d61a43293252ad732007c7070fdb112545fd https://git.kernel.org/stable/c/d2abc379071881798d20e2ac1d332ad855ae22f3 https://git.kernel.org/stable/c/516dbc6d16637430808c39568cbb6b841 •
