A race condition in the ZPA tunnel handler of affected versions of Zscaler Client Connector (ZCC) allows a heap corruption, resulting in a denial of service (client crash) and potentially arbitrary code execution in the context of the ZCC process.

——0In the Linux kernel, the following vulnerability has been resolved:
RDMA/mlx4: Fix mis-use of RCU in mlx4_srq_event()
Sashiko points out the radix_tree itself is RCU safe, but nothing ever
frees the mlx4_srq struct with RCU, and it isn't even accessed within the
RCU critical section. It also will crash if an event is delivered before
the srq object is finished initializing.
Use the spinlock since it isn't easy to make RCU work, use
refcount_inc_not_zero() to protect against partially initialized objects,
and order the refcount_set() to be after the srq is fully initialized.57dCVE-2026-236667.5 ALT69.4%
——21Improper input validation in .NET Framework allows an unauthorized attacker to deny service over a network.62dCVE-2026-39046.2 MED4.2%
——1Calling NSS-backed functions that support caching via nscd may call the
nscd client side code and in the GNU C Library version 2.36 under high
load on x86_64 systems, the client may call memcmp on inputs that are
concurrently modified by other processes or threads and crash.
The nscd client in the GNU C Library uses the memcmp function with
inputs that may be concurrently modified by another thread, potentially
resulting in spurious cache misses, which in itself is not a security
issue. However in the GNU C Library version 2.36 an optimized
implementation of memcmp was introduced for x86_64 which could crash
when invoked with such undefined behaviour, turning this into a
potential crash of the nscd client and the application that uses it.
This implementation was backported to the 2.35 branch, making the nscd
client in that branch vulnerable as well. Subsequently, the fix for
this issue was backported to all vulnerable branches in the GNU C
Library repository.
It is advised that distributions that may have cherry-picked the memcpy
SSE2 optimization in their copy of the GNU C Library, also apply the fix
to avoid the potential crash in the nscd client.63dCVE-2023-65467.0 ALT52.4%
——16A race condition was found in the GSM 0710 tty multiplexor in the Linux kernel. This issue occurs when two threads execute the GSMIOC_SETCONF ioctl on the same tty file descriptor with the gsm line discipline enabled, and can lead to a use-after-free problem on a struct gsm_dlci while restarting the gsm mux. This could allow a local unprivileged user to escalate their privileges on the system.40d
