pcp: pmpost symlink attack allows escalating pcp to root user

A vulnerability was found in Performance Co-Pilot PCP. This flaw can only be exploited if an attacker has access to a compromised PCP system account. The issue is related to the pmpost tool, which is used to log messages in the system. Under certain conditions, it runs with high-level privileges...

pcp: pmcd heap corruption through metric pmstore operations

A vulnerability was found in Performance Co-Pilot PCP. This flaw allows an attacker to send specially crafted data to the system, which could cause the program to misbehave or crash...

iperf3: possible denial of service

A flaw was found in iperf, a utility for testing network performance using TCP, UDP, and SCTP. A malicious or malfunctioning client can send less than the expected amount of data to the iperf server, which can cause the server to hang indefinitely waiting for the remainder or until the connection...

kernel: dpll: fix possible deadlock during netlink dump operation

A vulnerability was found in the Linux kernel, where an ABBA deadlock condition may be created if multiple CPUs attempt a DPLL netlink dump operation simultaneously. This deadlock could lead to performance issues...

kernel: perf: Fix event leak upon exit

A logical flaw exists in the Linux kernel. When a task is scheduled, pending sigtrap deliveries are deferred to the target task upon resuming to userspace via taskwork. However, failures are ignored while adding an event's callback to the taskwork engine. Since the last call for the event exit...

kernel: perf: Fix event leak upon exec and file release

Linux kernel perf pending task work is never waited upon the matching event release; in the case of a child event, released via freeevent directly, this can potentially result in a leaked event...

kernel: fs/proc: do_task_stat: use sig->stats_lock to gather the threads/children stats

A vulnerability was found in the dotaskstat function in the Linux kernel, where due to excessive lock contention, a potential hard lockup could be created. This can create a performance bottleneck and lead to kernel unresponsiveness...

kernel: nvdimm: Fix memleak of pmu attr_groups in unregister_nvdimm_pmu()

In the Linux kernel, the following vulnerability has been resolved: nvdimm: Fix memleak of pmu attrgroups in unregisternvdimmpmu Memory pointed by 'ndpmu-pmu.attrgroups' is allocated in function 'registernvdimmpmu' and is lost after 'kfreendpmu' call in function 'unregisternvdimmpmu'...

kernel: tcp: avoid too many retransmit packets

A vulnerability was found in the tcpretransmittimer function in the Linux kernel's TCP implementation. This issue occurs when a TCP socket uses TCPUSERTIMEOUT and the peer's window retracts to zero, leading to excessive retransmission of packets every two milliseconds for up to four minutes after...

kernel: wireguard: netlink: access device through ctx instead of peer

In the Linux kernel, the following vulnerability has been resolved: wireguard: netlink: access device through ctx instead of peer The previous commit fixed a bug that led to a NULL peer-device being dereferenced. It's actually easier and faster performance-wise to instead get the device from...

kernel: perf: hisi: Fix use-after-free when register pmu fails

In the Linux kernel, the following vulnerability has been resolved: perf: hisi: Fix use-after-free when register pmu fails When we fail to register the uncore pmu, the pmu context may not been allocated. The error handing will call cpuhpstateremoveinstance to call uncore pmu offline callback, whi...

Security Fixes: encoding/gob: golang: Calling Decoder.Decode on a message which contains deepl...

OpenSSL is vulnerable to a denial of service, caused by a flaw in the handling of RSA public keys by the EVP_PKEY_public_check() function

OpenSSL is vulnerable to a denial-of-service DoS issue due to how there is no restriction on RSA public key size, or the subsequent time spent processing such keys. Applications that use the EVPPKEYpubliccheck function to check RSA public keys obtained from potentially untrusted sources can be...
