Linux kernel 安全漏洞

The Linux kernel is the kernel used by the Linux Foundation's open source operating system Linux. A security vulnerability exists in the Linux kernel, which stems from a flaw in the Traffic Control TC subsystem, whereby, using a specific network configuration using the TC operation "mirred" to...

CVE-2022-4269

A flaw was found in the Linux kernel Traffic Control TC subsystem. Using a specific networking configuration redirecting egress packets to ingress using TC action "mirred" a local unprivileged user could trigger a CPU soft lockup ABBA deadlock when the transport protocol in use TCP or SCTP does a...

CVE-2022-4269

CVE-2022-4269 : Linux kernel Traffic Control (TC) vulnerability. When using the mirred action to redirect egress to ingress, a local unprivileged user may trigger a CPU soft lockup (ABBA deadlock) during TCP/SCTP retransmission, causing denial of service. Affected: Linux kernel TC subsystem. Root...

kernel: powerpc/rtas: Keep MSR[RI] set when calling RTAS

In the Linux kernel, the following vulnerability has been resolved: powerpc/rtas: Keep MSRRI set when calling RTAS RTAS runs in real mode MSRDR and MSRIR unset and in 32-bit big endian mode MSRSF,LE unset. The change in MSR is done in enterrtas in a relatively complex way, since the MSR value cou...

GSD-2022-1006653 mm/kmemleak: prevent soft lockup in kmemleak_scan()'s object iteration loops

mm/kmemleak: prevent soft lockup in kmemleakscan's object iteration loops This is an automated ID intended to aid in discovery of potential security vulnerabilities. The actual impact and attack plausibility have not yet been proven. This ID is fixed in Linux Kernel version v6.0.7 by commit...

Permanent lockup of tokens without recovery possible

Lines of code Vulnerability details Impact The callhook for whitelisted contracts adds an additional layer of complexity that can have multiple points of failure. If the execution of L2GraphTokenGateway.finalizeInboundTransfer fails indefinitely, there is currently no way to recover the...

ALPINE-CVE-2022-33748

lock order inversion in transitive grant copy handling As part of XSA-226 a missing cleanup call was inserted on an error handling path. While doing so, locking requirements were not paid attention to. As a result two cooperating guests granting each other transitive grants can cause locks to be...

A delegatee can frontrun the delegator's call to increaseUnlockTime to prevent the delegator to withdraw or quitlock

Lines of code Vulnerability details Impact Charlie and Alice both create a lock, with Alice's lock being longer than Charlie's. Charlie then delegates to Alice. At this point, if Charlie wants to unlock his tokens he can call withdraw or quitLock, but not with a delegation in place see 1, 2, so h...

Delegate can force users, who delegate to them, to increase their lock end

Lines of code Vulnerability details Impact If a user has votes delegated to them, they can force all users who delegated to them to increase their lock time with minimal negative effects to themselves. In my PoC, I prove that a user can lock minimal value and manipulate the users who delegated to...
