fs/proc: fix softlockup in __read_vmcore (part 2)

In the Linux kernel, the following vulnerability has been resolved: fs/proc: fix softlockup in __read_vmcore (part 2) Since commit 5cbcb62dddf5 ("fs/proc: fix softlockup in __read_vmcore") the number of softlockups in __read_vmcore at kdump time have gone down, but they still happen sometimes. In a memory constrained environment like the kdump image, a softlockup is not just a harmless message, but it can interfere with things like RCU freeing memory, causing the crashdump to get stuck. The …

hrtimers: Handle CPU state correctly on hotplug

In the Linux kernel, the following vulnerability has been resolved: hrtimers: Handle CPU state correctly on hotplug Consider a scenario where a CPU transitions from CPUHP_ONLINE to halfway through a CPU hotunplug down to CPUHP_HRTIMERS_PREPARE, and then back to CPUHP_ONLINE: Since hrtimers_prepare_cpu() does not run, cpu_base.hres_active remains set to 1 throughout. However, during a CPU unplug operation, the tick and the clockevents are shut down at CPUHP_AP_TICK_DYING. On return to the onli…

fs: Fix uninitialized value issue in from_kuid and from_kgid

In the Linux kernel, the following vulnerability has been resolved: fs: Fix uninitialized value issue in from_kuid and from_kgid ocfs2_setattr() uses attr->ia_mode, attr->ia_uid and attr->ia_gid in a trace point even though ATTR_MODE, ATTR_UID and ATTR_GID aren't set. Initialize all fields of newattrs to avoid uninitialized variables, by checking if ATTR_MODE, ATTR_UID, ATTR_GID are initialized, otherwise 0.

wifi: iwlwifi: mvm: Fix response handling in iwl_mvm_send_recovery_cmd()

In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: Fix response handling in iwl_mvm_send_recovery_cmd() 1. The size of the response packet is not validated. 2. The response buffer is not freed. Resolve these issues by switching to iwl_mvm_send_cmd_status(), which handles both size validation and frees the buffer.

net/sched: stop qdisc_tree_reduce_backlog on TC_H_ROOT

In the Linux kernel, the following vulnerability has been resolved: net/sched: stop qdisc_tree_reduce_backlog on TC_H_ROOT In qdisc_tree_reduce_backlog, Qdiscs with major handle ffff: are assumed to be either root or ingress. This assumption is bogus since it's valid to create egress qdiscs with major handle ffff: Budimir Markovic found that for qdiscs like DRR that maintain an active class list, it will cause a UAF with a dangling class pointer. In 066a3b5b2346, the concern was to avoid iter…

In the Linux kernel, the following vulnerability has been resolved: HID: core: zero-initialize the report buffer Since the report buffer is used by all kinds of drivers in various ways, let's zero-initialize it during allocation to make sure that it can't be ever used to leak kernel memory via specially-crafted report.

bpf: Fix out-of-bounds write in trie_get_next_key()

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix out-of-bounds write in trie_get_next_key() trie_get_next_key() allocates a node stack with size trie->max_prefixlen, while it writes (trie->max_prefixlen + 1) nodes to the stack when it has full paths from the root to leaves. For example, consider a trie with max_prefixlen is 8, and the nodes with key 0x00/0, 0x00/1, 0x00/2, ... 0x00/8 inserted. Subsequent calls to trie_get_next_key with _key with .prefixlen = 8 make …

netfilter: nft_payload: sanitize offset and length before calling skb_checksum()

In the Linux kernel, the following vulnerability has been resolved: netfilter: nft_payload: sanitize offset and length before calling skb_checksum() If access to offset + length is larger than the skbuff length, then skb_checksum() triggers BUG_ON(). skb_checksum() internally subtracts the length parameter while iterating over skbuff, BUG_ON(len) at the end of it checks that the expected length to be included in the checksum calculation is fully consumed.

net: phy: dp83869: fix memory corruption when enabling fiber

In the Linux kernel, the following vulnerability has been resolved: net: phy: dp83869: fix memory corruption when enabling fiber When configuring the fiber port, the DP83869 PHY driver incorrectly calls linkmode_set_bit() with a bit mask (1 << 10) rather than a bit number (10). This corrupts some other memory location -- in case of arm64 the priv pointer in the same structure. Since the advertising flags are updated from supported at the end of the function the incorrect line isn't needed at …

ext4: dax: fix overflowing extents beyond inode size when partially writing

In the Linux kernel, the following vulnerability has been resolved: ext4: dax: fix overflowing extents beyond inode size when partially writing The dax_iomap_rw() does two things in each iteration: map written blocks and copy user data to blocks. If the process is killed by user(See signal handling in dax_iomap_iter()), the copied data will be returned and added on inode size, which means that the length of written extents may exceed the inode size, then fsck will fail.

In the Linux kernel, the following vulnerability has been resolved: ext4: fix i_data_sem unlock order in ext4_ind_migrate() Fuzzing reports a possible deadlock in jbd2_log_wait_commit. This issue is triggered when an EXT4_IOC_MIGRATE ioctl is set to require synchronous updates because the file descriptor is opened with O_SYNC. This can lead to the jbd2_journal_stop() function calling jbd2_might_wait_for_commit(), potentially causing a deadlock if the EXT4_IOC_MIGRATE call races with a write(2…
