    ata: ahci: fail probe if BAR too small for claimed ports

    In the Linux kernel, the following vulnerability has been resolved: ata: ahci: fail probe if BAR too small for claimed ports When an AHCI controller is disabled in BIOS, its HOST_CAP register may contain a bogus value, e.g. 0xFFFFFFFF. Since CAP.NP (Number of Ports) is a zeroes based 5-bit register field, a value of 0x1f means 32 ports. If CAP.NP claims more ports than can physically fit within the mapped BAR region, accessing port registers beyond the BAR boundary causes a kernel panic. Add validation in ahci_init_one() to check that the BAR size is sufficient for the number of ports claimed in CAP.NP. The check calculates the required M

    net: qrtr: fix node refcount leak on ctrl packet alloc failure

    In the Linux kernel, the following vulnerability has been resolved: net: qrtr: fix node refcount leak on ctrl packet alloc failure qrtr_send_resume_tx() calls qrtr_node_lookup() which takes a reference on the returned node. If the subsequent call to qrtr_alloc_ctrl_packet() fails due to memory allocation failure, the function returns -ENOMEM without calling qrtr_node_release() to release the node reference. Add qrtr_node_release(node) before returning on the allocation failure path to properly release the reference.

    fs/ntfs3: validate index entry key bounds

    In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: validate index entry key bounds [BUG] A malformed NTFS directory index entry can advertise a key_size larger than the bytes actually present in its NTFS_DE payload. Directory lookup then passes that malformed key to cmp_fnames(), which can read past the end of the kmalloc'ed index buffer.

    In the Linux kernel, the following vulnerability has been resolved: ntfs3: fix out-of-bounds read in ntfs_dir_emit() and hdr_find_e() The bounds check in ntfs_dir_emit() compares fname->name_len (a character count) against e->size (a byte count) without accounting for the 2-byte-per-character UTF-16LE encoding or the ATTR_FILE_NAME header size: if (fname->name_len + sizeof(struct NTFS_DE) > le16_to_cpu(e->size)) This computes: name_len + 16 > e_size The correct check must account for the ATTR_FILE_NAME header (66 bytes before the name) and the UTF-16LE character size (2 bytes each): sizeof(NTFS_DE) + offsetof(ATTR_FILE_NAME, name) +

    dpaa2-switch: rework FDB management on the bridge leave path

    In the Linux kernel, the following vulnerability has been resolved: dpaa2-switch: rework FDB management on the bridge leave path On bridge leave, the dpaa2_switch_port_set_fdb() function always allocates a new FDB for the port which is becoming standalone. In case no FDB is found, then the port leaving a bridge will continue to use the current one. The above logic does not cover the case in which there are multiple bridges which have ports from the same DPSW instance. In this case, when the last port leaves bridge #1, it finds an unused FDB to switch to, but the old FDB is not marked as unused. Since the number of FDBs is equal to the numb

    net: dsa: sja1105: flower: reject cross-chip redirect

    In the Linux kernel, the following vulnerability has been resolved: net: dsa: sja1105: flower: reject cross-chip redirect dsa_port_from_netdev() may return a valid port from a different switch chip. Programming another chip's port index into the local hardware causes redirection to the wrong port, or an out-of-bounds access if the index exceeds the local chip's port count. Apply a minimal fix that adds a check to catch this case and adjusts the extack message. When cls->common.skip_sw is not set, the operation could instead redirect to the upstream port and let the software or upstream switch(es) handle the forward, but that is not address

    dpaa2-switch: fix handling of NAPI on the remove path

    In the Linux kernel, the following vulnerability has been resolved: dpaa2-switch: fix handling of NAPI on the remove path All the NAPI instances for a DPSW device are attached to the first switch port's net_device but shared by all ports. The NAPI instances get disabled only once the last port goes down. This causes an issue on the .remove() path where each port is unregistered and freed one at a time, causing the NAPI instances to be deleted even though they are not disabled. In order to avoid this, split up the unregister_netdev() calls from the free_netdev() so that we make sure all ports go down before we attempt a deletion of NAPI in

    wifi: iwlwifi: mvm: fix P2P-Device binding handling

    In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: fix P2P-Device binding handling Our binding handling for P2P-Device can run into the following scenario, as observed by our testing: - a station interface is connected on some channel - the P2P-Device does a remain-on-channel (ROC) on that channel - the ROC ends, and the P2P-Device is removed from the binding, but the phy_ctxt pointer is left around as a PHY cache so we don't need to recalibrate to the channel again and again in case it's not shared - a binding update by the station interface, even a removal, will re-add the P2P-Device t
