CWE-362

A race condition was addressed with improved state handling. This issue is fixed in macOS Catalina 10.15.5. An application may be able to execute arbitrary code with kernel privileges.

Adobe Acrobat and Reader versions 2020.006.20042 and earlier, 2017.011.30166 and earlier, 2017.011.30166 and earlier, and 2015.006.30518 and earlier have a race condition vulnerability. Successful exploitation could lead to security feature bypass.

The S. Siedle & Soehne SG 150-0 Smart Gateway before 1.2.4 allows local privilege escalation via a race condition in logrotate. By using an exploit chain, an attacker with access to the network can get root access on the gateway.

Gogs through 0.11.91 allows attackers to violate the admin-specified repo-creation policy due to an internal/db/repo.go race condition.

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”)

Race condition in subsystem for Intel(R) CSME versions before 12.0.70 and 14.0.45, Intel(R) SPS versions before E5_04.01.04.400 and E3_05.01.04.200 may allow an unauthenticated user to potentially enable escalation of privilege via physical access.
