In the Linux kernel, the following vulnerability has been resolved:
net: bonding: fix use-after-free in bond_xmit_broadcast()
bond_xmit_broadcast() reuses the original skb for the last slave
(determined by bond_is_last_slave()) and clones it for others.
Concurrent slave enslave/release can mutate the slave list during
RCU-protected iteration, changing which slave is "last" mid-loop.
This causes the original skb to be double-consumed (double-freed).
Replace the racy bond_is_last_slave() check with a simple index
comparison (i + 1 == slaves_count) against the pre-snapshot slave
count taken via READ_ONCE() before the loop. This preserves the
zero-copy optimization for the last slave while making the "last"
determination stable against concurrent list mutations.
The UAF can trigger the following crash:

CVE-2025-71268 [HIGH] Linux kernel vulnerabilities
Title: Linux kernel vulnerabilities
Summary: Several security issues were fixed in the Linux kernel.
It was discovered that the Linux kernel algif_aead module did not properly
handle in-place cryptographic operations. This flaw is known as Copy Fail.
A local attacker could use this to escalate privileges, or possibly escape
a container. (CVE-2026-31431)
Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.
This update corrects flaws in the following subsystems:
- ARM64 architecture;
- x86 architecture;
- Cryptographic API;
- Compute Acceleration Framework;
- Drivers core;
- Null block device driver;
- Ublk userspace block driver;
- Bluetooth drivers;

kernel: Linux kernel: Use-after-free in bonding driver leads to denial of service

CVE-2026-31419 [HIGH] CWE-416 kernel: Linux kernel: Use-after-free in bonding driver leads to denial of service
kernel: Linux kernel: Use-after-free in bonding driver leads to denial of service
A flaw was found in the Linux kernel's bonding driver. A local attacker with low privileges could exploit a use-after-free vulnerability in the `bond_xmit_broadcast()` function. This occurs due to a race condition during concurrent slave enslave/release operations, which can lead to the original socket buffer (skb) being double-freed. Successful exploitation of this flaw can result in a system crash, leading to a denial of service.
Statement: This is an Important impact flaw affecting the Linux kernel's bonding driver in Red Hat Enterprise Linux 6, 8.8 and later, 9.2 and later, and 10, as well as Red Hat In-Vehicle OS 2.0. A local attacker with low privileges could trigger a use-after-free vulnerability, le

net: bonding: fix use-after-free in bond_xmit_broadcast()
bond_xmit_broadcast()
In the Linux kernel, the following vulnerability has been resolved:
net: bonding: fix use-after-free in bond_xmit_broadcast()
bond_xmit_broadcast() reuses the original skb for the last slave
(determined by bond_is_last_slave()) and clones it for others.
Concurrent slave enslave/release can mutate the slave list during
RCU-protected iteration, changing which slave is "last" mid-loop.
This causes the original skb to be double-consumed (double-freed).
Replace the racy bond_is_last_slave() check with a simple index
comparison (i + 1 == slaves_count) against the pre-snapshot slave
count taken via READ_ONCE() before the loop. This preserves the
zero-copy optimization for the last slave while making the "last"
determination stable against concurrent list mutations.
The UAF can trigger the fol

[MEDIUM] Patch Tuesday - April 2026
Microsoft is publishing 167 vulnerabilities on April 2026 Patch Tuesday . Microsoft is aware of exploitation in the wild for one of today’s vulnerabilities, and public disclosure for one other. Microsoft evaluates 19 of the vulnerabilities published today as more likely to see future exploitation. So far this month, Microsoft has provided patches to address 80 browser vulnerabilities, which are not included in the Patch Tuesday count above.
## Increasing volumes of vulnerabilities
Regular Patch Tuesday watchers will know that these vulnerability totals are significantly higher than usual, especially the browser numbers. Late last week, Microsoft published patches to resolve more than 60 browser vulnerabilities in a single day, which is a new record in that very specific category.
