    fuse: copy request headers via a stack buffer for io-uring

    In the Linux kernel, the following vulnerability has been resolved: fuse: copy request headers via a stack buffer for io-uring The fuse-io-uring transport copies req->in.h out to the ring in fuse_uring_copy_to_ring() and req->out.h back in fuse_uring_commit(). Both headers live inside the fuse_request slab object, whose cache (fuse_req_cachep) is created without a usercopy whitelist, so copying them directly to/from userspace trips CONFIG_HARDENED_USERCOPY and panics: usercopy: Kernel memory exposure attempt detected from SLUB object 'fuse_request' (offset 56, size 40)! kernel BUG at mm/usercopy.c:102! Oops: invalid opcode: 0000 [#

    crypto: iaa - unmap dst before software fallback on decompress

    In the Linux kernel, the following vulnerability has been resolved: crypto: iaa - unmap dst before software fallback on decompress On a hardware analytics error, decompress retries through the software fallback, which writes req->dst with the CPU while it is still mapped DMA_FROM_DEVICE. With SWIOTLB active the later dma_unmap_sg() copies the stale bounce buffer over req->dst, corrupting the result. Unmap before the fallback runs. The async path unmaps inline; the sync path signals the retry with -EAGAIN so iaa_comp_adecompress() runs the fallback after unmapping.

    wifi: mwifiex: Detach sync cmd buffer on interrupted wait

    In the Linux kernel, the following vulnerability has been resolved: wifi: mwifiex: Detach sync cmd buffer on interrupted wait mwifiex synchronous commands keep the caller-provided data buffer in cmd_node->data_buf. Several callers pass stack-allocated objects there. If wait_event_interruptible_timeout() is interrupted, the caller can return and release that stack object while the firmware command is still the current command. A late firmware response then reaches the normal response handler, which can copy data through cmd_node->data_buf into the stale stack address. This fixes a stack corruption observed during repeated association and d

    wifi: rtlwifi: rtl8192du: check QoS TID before indexing tids

    In the Linux kernel, the following vulnerability has been resolved: wifi: rtlwifi: rtl8192du: check QoS TID before indexing tids rtl92du_tx_fill_desc() uses ieee80211_get_tid() to read the QoS TID from the 802.11 header and then uses it as an index into sta_entry->tids[]. ieee80211_get_tid() returns the low 4-bit QoS TID value, so the result can be in the range 0..15. rtlwifi only allocates MAX_TID_COUNT entries for sta_entry->tids[], and MAX_TID_COUNT is 9. A QoS TID greater than 8 therefore indexes past the aggregation state array. Keep the default RTL_AGG_STOP state for out-of-range TIDs, matching rtl92cu_tx_fill_desc(). This issue was

    In the Linux kernel, the following vulnerability has been resolved: wifi: rtw88: Fix potential memory leak in rtw_txq_push_skb() The skb passed to the rtw_hci_tx_write() is expected to be freed when the function fails, but the error path in rtw_txq_push_skb() does not free the skb before returning. This can lead to a memory leak in rtw_txq_push() where a dequeued skb is passed to rtw_txq_push_skb().

    wifi: rtw88: pci: fix resource leak on failed NAPI setup

    In the Linux kernel, the following vulnerability has been resolved: wifi: rtw88: pci: fix resource leak on failed NAPI setup rtw_pci_probe() allocates PCI resources through rtw_pci_setup_resource() before it sets up NAPI. If rtw_pci_napi_init() fails, the error path jumps straight to err_pci_declaim and skips rtw_pci_destroy(), leaving the PCI resources allocated by rtw_pci_setup_resource() behind. Add a dedicated cleanup label for the NAPI setup failure path so probe destroys the PCI resources. The bug was first flagged by an experimental analysis tool we are developing for kernel memory-management bugs while analyzing current mainline k

    In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7615: avoid waiting for mac work under the mt76 mutex mt7615_suspend() acquired the mt76 mutex and then called cancel_delayed_work_sync() on mac_work. mt7615_mac_work() acquires the same mutex via mt7615_mutex_acquire() at the top of the worker, so if mac_work is already running and blocked on the mutex, the suspend path deadlocks waiting for the work it holds the mutex against. Flush scan_work and mac_work before taking the mutex, matching the suspend paths in mt7921 and mt7925. scan_work only takes the mt76 spinlock, but moving it keeps the sequence consi

    In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7996: fix TX DMA mapping leak for AddBA req frames mt7996/mt7992 hand the firmware a HW MAC-TXP for AddBA req action frames (MT_TXD7_MAC_TXD, set in mt7996_mac_write_txwi_80211()), but are otherwise FW-TXP devices. On tx free mt76_connac_txp_skb_unmap() therefore decodes the per-frame txp as a struct mt76_connac_fw_txp. For a MAC-TXP the fw_txp.nbuf byte aliases the AddBA TID word (MT_TXP1_TID_ADDBA), which is always zero, so the unmap loop runs zero times and the skb DMA mapping in buf[1] is never unmapped. buf[1].skip_unmap is set unconditionally, so the gen

    vsock/virtio: flush works in dependency order

    In the Linux kernel, the following vulnerability has been resolved: vsock/virtio: flush works in dependency order virtio_vsock_remove() stops the virtqueues and then flushes each work item before freeing the enclosing virtio_vsock. The current order does not account for dependencies between those items: tx_work may queue send_pkt_work, and send_pkt_work may queue rx_work. In particular, send_pkt_work can set restart_rx and release tx_lock. The remove path can then stop the queues and flush rx_work before send_pkt_work queues it. Although the later send_pkt_work flush waits for that producer to finish, nothing waits for the newly queued r

    w1: ds28e17: reject an oversize length on an I2C block read

    In the Linux kernel, the following vulnerability has been resolved: w1: ds28e17: reject an oversize length on an I2C block read w1_f19_i2c_master_transfer() is the master_xfer for the DS28E17 1-Wire to I2C bridge. On an I2C_M_RECV_LEN read, it takes the length from the device. The downstream slave puts a length byte in buf[0]. The driver then reads that many bytes into buf[1] with w1_f19_i2c_read(). buf[0] is controlled by the device and can be 0 to 255. w1_f19_i2c_read() only rejects a zero count. The caller buffer is I2C_SMBUS_BLOCK_MAX + 2, so 34 bytes. A length above 32 makes the read run past it, up to about 222 bytes out of bounds.

Also preserve an interrupted wait's original error code instead of converting it to -ETIMEDOUT inside the helper.

    In the Linux kernel, the following vulnerability has been resolved: sysctl: move the "cad_pid" entry from pid_table[] to kern_reboot_table[] cad_pid is global, and kill_cad_pid() is only used in the root namespace. However, due to pid_table_root_permissions(), a non-root user can unshare pid/user namespaces and modify it from the child namespace. This makes no sense and is simply wrong. Move it to kern_reboot_table[] where it logically belongs; this ensures that only GLOBAL_ROOT_UID can read/modify this sysctl. Note that this patch doesn't preserve "#ifdef CONFIG_PROC_SYSCTL" around the "cad_pid"; CONFIG_PROC_SYSCTL selects CONFIG_SYSCTL
