dm_table_create in drivers/md/dm-table.c in the Linux kernel through 6.7.4 can attempt to (in alloc_targets) allocate more than INT_MAX bytes, and crash, because of a missing check for struct dm_ioctl.target_count. (CVE-2023-52429)

In the Linux kernel, the following vulnerability has been resolved:

net: prevent mss overflow in skb_segment()

Once again syzbot is able to crash the kernel in skb_segment() [1]

GSO_BY_FRAGS is a forbidden value, but unfortunately the followingcomputation in skb_segment() can reach it quite easily :

mss = mss * partial_segs;

65535 = 3 * 5 * 17 * 257, so many initial values of mss can lead toa bad final result.

Make sure to limit segmentation so that the new mss value is smallerthan GSO_BY_FRAGS.

---truncated--- (CVE-2023-52435)

In the Linux kernel, the following vulnerability has been resolved:

drm: Don't unref the same fb many times by mistake due to deadlock handling (CVE-2023-52486)

ceph: fix deadlock or deadcode of misusing dget() (CVE-2023-52583)

In the Linux kernel, the following vulnerability has been resolved:

IB/ipoib: Fix mcast list locking (CVE-2023-52587)

In the Linux kernel, the following vulnerability has been resolved:

In the Linux kernel, the following vulnerability has been resolved:

ext4: avoid online resizing failures due to oversized flex bg (CVE-2023-52622)

In the Linux kernel, the following vulnerability has been resolved:

SUNRPC: Fix a suspicious RCU usage warning (CVE-2023-52623)

A flaw was found in the ATA over Ethernet (AoE) driver in the Linux kernel. The aoecmd_cfg_pkts() function improperly updates the refcnt on `struct net_device`, and a use-after-free can be triggered by racing between the free on the struct and the access through the `skbtxq` global queue. This could lead to a denial of service condition or potential code execution. (CVE-2023-6270)

A vulnerability was found in vhost_new_msg in drivers/vhost/vhost.c in the Linux kernel, which does not properly initialize memory in messages passed between virtual guests and the host operating system in the vhost/vhost.c:vhost_new_msg() function. This issue can allow local privileged users to read some kernel memory contents when reading from the /dev/vhost-net device file. (CVE-2024-0340)

A vulnerability was reported in the Open vSwitch sub-component in the Linux Kernel. The flaw occurs when a recursive operation of code push recursively calls into the code block. The OVS module does not validate the stack depth, pushing too many frames and causing a stack overflow. As a result, this can lead to a crash or other related issues. (CVE-2024-1151)

A Speculative Race Condition (SRC) vulnerability that impacts modern CPU architectures supporting speculative execution (related to Spectre V1) has been disclosed. An unauthenticated attacker can exploit this vulnerability to disclose arbitrary data from the CPU using race conditions to access the speculative executable code paths. (CVE-2024-2193)

copy_params in drivers/md/dm-ioctl.c in the Linux kernel through 6.7.1 can attempt to allocate more than INT_MAX bytes, and crash, because of a missing param_kernel->data_size check. This is related to ctl_ioctl. (CVE-2024-23851)

In the Linux kernel, the following vulnerability has been resolved:

netfilter: nft_set_rbtree: skip end interval element from gc

rbtree lazy gc on insert might collect an end interval element that hasbeen just added in this transactions, skip end interval elements thatare not yet active. (CVE-2024-26581)

In the Linux kernel, the following vulnerability has been resolved:

KVM: arm64: vgic-its: Avoid potential UAF in LPI translation cache (CVE-2024-26598)

In the Linux kernel, the following vulnerability has been resolved:

sched/membarrier: reduce the ability to hammer on sys_membarrier

On some systems, sys_membarrier can be very expensive, causing overallslowdowns for everything. So put a lock on the path in order toserialize the accesses to prevent the ability for this to be called attoo high of a frequency and saturate the machine. (CVE-2024-26602)

In the Linux kernel, the following vulnerability has been resolved:

llc: call sock_orphan() at release time (CVE-2024-26625)

In the Linux kernel, the following vulnerability has been resolved:

blk-mq: fix IO hang from sbitmap wakeup race (CVE-2024-26671)

In the Linux kernel, the following vulnerability has been resolved:

netfilter: nft_ct: sanitize layer 3 and 4 protocol number in custom expectations (CVE-2024-26673)

In the Linux kernel, the following vulnerability has been resolved:

ppp_async: limit MRU to 64K (CVE-2024-26675)

In the Linux kernel, the following vulnerability has been resolved:

inet: read sk->sk_family once in inet_recv_error() (CVE-2024-26679)

mm/writeback: fix possible divide-by-zero in wb_dirty_limits(), again (CVE-2024-26720)

In the Linux kernel, the following vulnerability has been resolved:

netfilter: ipset: fix performance regression in swap operation (CVE-2024-26910)

In the Linux kernel, the following vulnerability has been resolved:

scsi: Revert scsi: fcoe: Fix potential deadlock on &fip->ctlr_lock (CVE-2024-26917)

In the Linux kernel, the following vulnerability has been resolved:

tracing/trigger: Fix to return error if failed to alloc snapshot (CVE-2024-26920)

In the Linux kernel, the following vulnerability has been resolved:
