CVE-2022-48985 | 1 Linux | 1 Linux Kernel | 2024-11-07 | 4.7 Medium |
In the Linux kernel, the following vulnerability has been resolved: net: mana: Fix race on per-CQ variable napi work_done After calling napi_complete_done(), the NAPIF_STATE_SCHED bit may be cleared, and another CPU can start napi thread and access per-CQ variable, cq->work_done. If the other thread (for example, from busy_poll) sets it to a value >= budget, this thread will continue to run when it should stop, and cause memory corruption and panic. To fix this issue, save the per-CQ work_done variable in a local variable before napi_complete_done(), so it won't be corrupted by a possible concurrent thread after napi_complete_done(). Also, add a flag bit to advertise to the NIC firmware: the NAPI work_done variable race is fixed, so the driver is able to reliably support features like busy_poll. | ||||
CVE-2020-8834 | 5 Canonical, Ibm, Linux and 2 more | 5 Ubuntu Linux, Power8, Linux Kernel and 2 more | 2024-09-16 | 6.5 Medium |
KVM in the Linux kernel on Power8 processors has a conflicting use of HSTATE_HOST_R1 to store r1 state in kvmppc_hv_entry plus in kvmppc_{save,restore}_tm, leading to a stack corruption. Because of this, an attacker with the ability run code in kernel space of a guest VM can cause the host kernel to panic. There were two commits that, according to the reporter, introduced the vulnerability: f024ee098476 ("KVM: PPC: Book3S HV: Pull out TM state save/restore into separate procedures") 87a11bb6a7f7 ("KVM: PPC: Book3S HV: Work around XER[SO] bug in fake suspend mode") The former landed in 4.8, the latter in 4.17. This was fixed without realizing the impact in 4.18 with the following three commits, though it's believed the first is the only strictly necessary commit: 6f597c6b63b6 ("KVM: PPC: Book3S PR: Add guest MSR parameter for kvmppc_save_tm()/kvmppc_restore_tm()") 7b0e827c6970 ("KVM: PPC: Book3S HV: Factor fake-suspend handling out of kvmppc_save/restore_tm") 009c872a8bc4 ("KVM: PPC: Book3S PR: Move kvmppc_save_tm/kvmppc_restore_tm to separate file") | ||||
CVE-2022-21806 | 1 Anker | 2 Eufy Homebase 2, Eufy Homebase 2 Firmware | 2024-09-16 | 9.8 Critical |
A use-after-free vulnerability exists in the mips_collector appsrv_server functionality of Anker Eufy Homebase 2 2.1.8.5h. A specially-crafted set of network packets can lead to remote code execution. The device is exposed to attacks from the network. | ||||
CVE-2024-34731 | 1 Google | 1 Android | 2024-08-19 | 7.7 High |
In multiple functions of TranscodingResourcePolicy.cpp, there is a possible memory corruption due to a race condition. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation. | ||||
CVE-2021-21941 | 1 Anker | 2 Eufy Homebase 2, Eufy Homebase 2 Firmware | 2024-08-03 | 9.0 Critical |
A use-after-free vulnerability exists in the pushMuxer CreatePushThread functionality of Anker Eufy Homebase 2 2.1.6.9h. A specially-crafted set of network packets can lead to remote code execution. |
