Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: scsi: hisisas: Freeing irq vectors in order for v3 HW If the driver probe fails to request the channel IRQ or fatal IRQ, the driver will free the IRQ vectors before freeing the IRQs in freeirq. This will cause a kernel BUG like...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: KVM: SVM – Fix for a panic occurring on an out-of-bounds guest IRQ. Since the guestIRQ comes from the KVMIRQFD API call, it may trigger a crash in svmupdatepiirte, due to an out-of-bounds access. Crash output: pid: 22218 task:...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: scsi: qla2xxx: Fix scheduling while atomic The driver makes a call to the midlayer function fcremoteportdelete, which can put the thread to sleep.

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: net: stmmac: Fix for accessing freed irq affinityhint In stmmacrequestirqmultimsi, a pointer to the stack variable cpumask is passed to irqsetaffinityhint. This value is stored in irqdesc-affinityhint, but once...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: drm/msm/dp: Do not complete dpauxcmdfifotx if the irq is not for aux transfer. The DP controller handles three possible interrupt sources: HPDstatus, controller state changes, and Aux read/write transactions. At every irq, the...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: x86/i8259: The legacy PIC interrupts have been marked with IRQLEVEL. Baoquan reported that after triggering a crash, the subsequent boot process fails about half of the time. This occurs due to a NULL pointer dereference in the...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: net: phy: dp83822: Fix null pointer access on DP83825/DP83826 devices The probe function is only used for the DP83822 PHY; the private data pointer remains uninitialized for the smaller DP83825/26 models. While all uses of the...

In the Linux kernel, the following vulnerabilities have been resolved: net/iucv: Fixed the size of interrupt data iucvirqdata needs to be 4 bytes larger. These bytes are not used by the iucv module, but are written by the z/VM hypervisor in case a CPU is deconfigured. Reported as: BUG...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: SPI: sun6i – Fixing the race condition between DMA RX transfer completion and RX FIFO drain. Previously, the transfer-completion interrupt would immediately drain the RX FIFO to read any remaining data in the FIFO into the RX...

In the Linux kernel, the following vulnerability has been resolved: serial: 8250port: Check IRQ data before use If the leaf driver wishes to use IRQ polling irq = 0, and the IIR register indicates that an interrupt occurred in the 8250 hardware, the IRQ data can be NULL. In such cases, we need to...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: media: rkisp1: Fixed the race condition related to interrupt disable. In rkisp1ispstop and rkisp1csidisable, the driver masks the interrupts and then assumes that the interrupt handler will not be running. However, this is not...
