2024-05-21 CVE-2021-47373 In the Linux kernel, the following vulnerability has been resolved: irqchip/gic-v3-its: Fix potential VPE leak on error In its_vpe_irq_domain_alloc, when its_vpe_init() returns an error, there is an off-by-one in the number of VPEs to be freed. Fix it by simply passing the number of VPEs allocated, which is the index of the loop iterating over the VPEs. [maz: fixed commit message] Linux_kernel 5.5
2024-02-28 CVE-2021-46992 In the Linux kernel, the following vulnerability has been resolved: netfilter: nftables: avoid overflows in nft_hash_buckets() Number of buckets being stored in 32bit variables, we have to ensure that no overflows occur in nft_hash_buckets() syzbot injected a size == 0x40000000 and reported: UBSAN: shift-out-of-bounds in ./include/linux/log2.h:57:13 shift exponent 64 is too large for 64-bit type 'long unsigned int' CPU: 1 PID: 29539 Comm: syz-executor.4 Not tainted 5.12.0-rc7-syzkaller...

2024-02-28 CVE-2021-46993 In the Linux kernel, the following vulnerability has been resolved: sched: Fix out-of-bound access in uclamp Util-clamp places tasks in different buckets based on their clamp values for performance reasons. However, the size of buckets is currently computed using a rounding division, which can lead to an off-by-one error in some configurations. For instance, with 20 buckets, the bucket size will be 1024/20=51. A task with a clamp of 1024 will be mapped to bucket id 1024/51=20.... Linux_kernel 7.1
2024-02-28 CVE-2021-46997 In the Linux kernel, the following vulnerability has been resolved: arm64: entry: always set GIC_PRIO_PSR_I_SET during entry Zenghui reports that booting a kernel with "irqchip.gicv3_pseudo_nmi=1" on the command line hits a warning during kernel entry, due to the way we manipulate the PMR. Early in the entry sequence, we call lockdep_hardirqs_off() to inform lockdep that interrupts have been masked (as the HW sets DAIF wqhen entering an exception). Architecturally PMR_EL1 is not affected... Linux_kernel 5.5
2024-05-21 CVE-2021-47260 In the Linux kernel, the following vulnerability has been resolved: NFS: Fix a potential NULL dereference in nfs_get_client() None of the callers are expecting NULL returns from nfs_get_client() so this code will lead to an Oops. It's better to return an error pointer. I expect that this is dead code so hopefully no one is affected. Linux_kernel 5.5
2024-05-21 CVE-2021-47264 In the Linux kernel, the following vulnerability has been resolved: ASoC: core: Fix Null-point-dereference in fmt_single_name() Check the return value of devm_kstrdup() in case of Null-point-dereference. Linux_kernel 5.5
2024-05-21 CVE-2021-47269 In the Linux kernel, the following vulnerability has been resolved: usb: dwc3: ep0: fix NULL pointer exception There is no validation of the index from dwc3_wIndex_to_dep() and we might be referring a non-existing ep and trigger a NULL pointer exception. In certain configurations we might use fewer eps and the index might wrongly indicate a larger ep index than existing. By adding this validation from the patch we can actually report a wrong index back to the caller. In our usecase we... Linux_kernel 5.5
2024-05-21 CVE-2021-47270 In the Linux kernel, the following vulnerability has been resolved: usb: fix various gadgets null ptr deref on 10gbps cabling. This avoids a null pointer dereference in f_{ecm,eem,hid,loopback,printer,rndis,serial,sourcesink,subset,tcm} by simply reusing the 5gbps config for 10gbps. Linux_kernel 5.5
2024-05-21 CVE-2021-47280 In the Linux kernel, the following vulnerability has been resolved: drm: Fix use-after-free read in drm_getunique() There is a time-of-check-to-time-of-use error in drm_getunique() due to retrieving file_priv->master prior to locking the device's master mutex. An example can be seen in the crash report of the use-after-free error found by Syzbot: https://syzkaller.appspot.com/bug?id=148d2f1dfac64af52ffd27b661981a540724f803 In the report, the master pointer was used after being freed....

2024-05-21 CVE-2021-47281 In the Linux kernel, the following vulnerability has been resolved: ALSA: seq: Fix race of snd_seq_timer_open() The timer instance per queue is exclusive, and snd_seq_timer_open() should have managed the concurrent accesses. It looks as if it's checking the already existing timer instance at the beginning, but it's not right, because there is no protection, hence any later concurrent call of snd_seq_timer_open() may override the timer instance easily. This may result in UAF, as the... Linux_kernel 7.0
