CVE-2025-39819

The Linux Kernel, the operating system core itself.

Security Fix(es):

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

Bluetooth: hci_conn: Use disable_delayed_work_sync

This makes use of disable_delayed_work_sync instead cancel_delayed_work_sync as it not only cancel the ongoing work but also disables new submit which is disarable since the object holding the work is about to be freed.(CVE-2024-56591)

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

ipv6: Fix memleak of nhc_pcpu_rth_output in fib_check_nh_v6_gw().

fib_check_nh_v6_gw() expects that fib6_nh_init() cleans up everything when it fails.

Commit 7dd73168e273 ("ipv6: Always allocate pcpu memory in a fib6_nh") moved fib_nh_common_init() before alloc_percpu_gfp() within fib6_nh_init() but forgot to add cleanup for fib6_nh->nh_common.nhc_pcpu_rth_output in case it fails to allocate fib6_nh->rt6i_pcpu, resulting in memleak.

Let's call fib_nh_common_release() and clear nhc_pcpu_rth_output in the error path.

Note that we can remove the fib6_nh_release() call in nh_create_ipv6() later in net-next.git.(CVE-2025-22005)

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

fs/ntfs3: Fix a couple integer overflows on 32bit systems

On 32bit systems the "off + sizeof(struct NTFS_DE)" addition can have an integer wrapping issue. Fix it by using size_add().(CVE-2025-22081)

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

jfs: Prevent copying of nlink with value 0 from disk inode

syzbot report a deadlock in diFree. [1]

When calling "ioctl$LOOP_SET_STATUS64", the offset value passed in is 4, which does not match the mounted loop device, causing the mapping of the mounted loop device to be invalidated.

When creating the directory and creating the inode of iag in diReadSpecial(), read the page of fixed disk inode (AIT) in raw mode in read_metapage(), the metapage data it returns is corrupted, which causes the nlink value of 0 to be assigned to the iag inode when executing copy_from_dinode(), which ultimately causes a deadlock when entering diFree().

To avoid this, first check the nlink value of dinode before setting iag inode.

In the Linux kernel, the following vulnerability has been resolved: fs/smb: Fix inconsistent refcnt update A possible inconsistent update of refcount was identified in smb2_compound_op. Such inconsistent update could lead to possible resource leaks. Why it is a possible bug: 1. In the comment section of the function, it clearly states that the reference to cfile should be dropped after calling this function. 2. Every control flow path would check and drop the reference to cfile, except the patched one. 3. Existing callers would not handle refcount update of cfile if -ENOMEM is returned. To fix the bug, an extra goto label "out" is added, to make sure that the cleanup logic would always be respected. As the problem is caused by the allocation failure of vars, the cleanup logic between label "finished" and "out" can be safely ignored. According to the definition of function is_replayable_error, the error code of "-ENOMEM" is not recoverable. Therefore, the replay logic also gets ignored.

Qualys discovered that several vulnerabilities existed in the AppArmor Linux kernel Security Module (LSM). An unprivileged local attacker could use these issues to load, replace, and remove arbitrary AppArmor profiles causing denial of service, exposure of sensitive information (kernel memory), local privilege escalation, or possibly escape a container.

An unprivileged local attacker could use these issues to load, replace, and remove arbitrary AppArmor profiles causing denial of service, exposure of sensitive information (kernel memory), local privilege escalation, or possibly escape a container. (LP: #2143853)

It was discovered that improper initialization of CPU cache memory could allow a local attacker with hypervisor access to overwrite SEV-SNP guest memory resulting in loss of data integrity. (CVE-2024-36331)

Oleksii Oleksenko, Cedric Fournet, Jana Hofmann, Boris Köpf, Stavros Volos, and Flavien Solt discovered that some AMD processors may allow an attacker to infer data from previous stores, potentially resulting in the leakage of privileged information. A local attacker could possibly use this to expose sensitive information. (CVE-2024-36350, CVE-2024-36357)

Josh Eads, Kristoffer Janke, Eduardo Vela Nava, Tavis Ormandy, and Matteo Rizzo discovered that some AMD Zen processors did not properly verify the signature of CPU microcode. This flaw is known as EntrySign. A privileged attacker could possibly use this issue to cause load malicious CPU microcode causing loss of integrity and confidentiality. (CVE-2024-36347)
